While certainly not always the case, Devo definately has a few songs that can count as this, particularly Come Back Jonee, The Day My Baby Gave Me a Surprize, Whip It, That's Pep, Gates of Steel, Smart Patrol/Mr. DNA, Time Out For Fun, That's Good, Through Being Cool, Worried Man, and the Theme from Dr. Detroit.
The accompanying videos for the latter two also qualify, the one for Worried Man being a fun romp featuring Booji Boy, and the Theme from Dr. Detroit being a montage of random slapstick and tricks with a bluescreen.
In the Dreamy Theater PV for "Double Lariat", Takoluka makes an appearance and just happily flies around the stage. The end has her peeking out from behind the stage scenery to take one last wave at the viewer, as if to say "Hiiiiii!"
Ob-La-Di, Ob-La-Da is one of the most cheerful songs ever written, telling a nice small-town love story with a lovely happy ending. It even ends with the lines, "And if you want some fun / sing OB-LA-DI-LA-DA!", before one of the Beatles puts on a silly high-pitched voice and squeaks, "Thank you!" while one of his bandmates laughs.
George Harrison, who was a tank of sweet dreams fuel in his own right. Just listen to "All Things Must Pass." You could practically drift away on it. There's a reason George has been called "the soul of the Beatles."
The Beach Boys practically run on this trope, at least most of the time.
From "All Summer Long" there's "I Get Around", which is about just being young and having fun, and what could be better than that?
Owl City + Carly Rae Jepsen = Good Time. Carly may be famous for Call Me Maybe, but she also did well in this nice, uplifting song with Owl City.
"To the Sky". It's simply impossible to hear that song without ending up in at least a slightly better mood than beforehand.
"Angels" and "Honey And The Bee" deserve mentioning, the former being a happy, peppy song that can easily make even the most paranoid feel safe, and the latter being an adorable love song told from the perspective of a cute little bug.
Carly Rae Jepsen herself. "This Kiss" is one of those songs that's just so upbeat and infectious it's almost criminal. In the video she wears many beautiful costumes, and it ends with her kissing a guy underwater.
As the 2013 Candies Girl, Jepsen posed for some very beautiful pics.
Demi Lovato's video for the song "Gift of a Friend" is so beautiful. She even wears white in the video, which doubles as a Sweet Dream.
As it is apparently Radiohead's goal to branch out into as many genres as they possibly can, it was only a matter of time before they created "Worrywort," possibly the world's most uplifting 8-bit alternative ambient post-punk post-rock dance-rock.
Almost anything by Donna Summer qualifies. Her music seems to emanate from a world of brightly colored lights and nonstop dancing and love. How can you NOT want to dance to Donna?
Girls' Generation's Gee and Kissing You are my happy place songs. Dear Mom is a good one, too, since it was made specifically to be a love letter to the members' mothers.
Connor Kirby-Long (aka Grandma, Khonnor, I, Cactus, and others) has a discography that's outright rife with this. Even at its darkest, Long's work (most of it, anyway) radiates a light, warm, atmosphere that's strong enough to make you feel as though everything will turn out alright.
The Sanity Song. "We hear every damn day about our fragile country. We hear every damn day about the brink of catastrophe, and that it's a shame that we can't work together. But the truth is, we do. We work together to get things done every damn day."]]
Cymbaline from More. Calming instrumentals, soft vocals, acoustic guitar, piano, and even a scat solo. Perfect to fall asleep to
"Outside The Wall" is a gentle reminder that as long as there are people left on the planet, somebody cares about you. The version heard in the album's film adaptation sounds like a gentle lullaby.
Actually debatable as to whether or not "Outside the Wall" can be counted or not, and it's pretty much based on context. By itself, it is absolutely sweet dreams fuel. But for everyone who has listened to the album and given its link to the beginning some thought, it very quickly takes a nosedive into fridge horror territory.
The 2005 reunion. Everything about it is heartwarming. And their live shows in general are usually something to behold.
Especially in the acoustic version. Skip to 2:35 to hear it- and it's nice to see how happy and peaceful the band look whilst playing.
Their song "All Alone" has a beautiful bridge section where Martina Topley takes over with her ethereal vocal display. It's incredible.
"Empire Ants" is just nonstop concentrated SDF. The gentle and mellow intro alone is enough to fit on this page, but it even qualifies when the song starts picking up and the synths and beats are introduced.
Emilie Autumn, has some sweet dream making songs such as Across The Sky, and Remember.
and her covers of such songs as Leclair-Tabourin, Vitali-Chaconne and Crazy He Calls Me.
Really, the whole Dream Pop genre comes under this.
Britney Spears has some sweet dream giving songs such as Strangest Love, Trip To Your Heart, Heaven On Earth, When I Found You, Everyday and State Of Grace
The Veronicas have "I Could Get Used To This" a song basically describing the(ir) ultimate boyfriend.
Also putting Colbie Caillat here. Particularly "Magic" and "Oxygen", but most of her music would fit here, either uplifting or loving or telling you it's okay to be afraid sometimes of little things like commitment (Tied Down) or of failure (It Stops Today)
Quite a few LM.C songs. Some of the best examples are "Punky Heart" ("You're crying all alone but if you can just smile then it doesn't matter if the whole world's your enemy"), "Optimisland" ("The blue color of the sky that we always see as the color of tears just does not look that bad if I am with you, right?"), and "Ah Hah!" ("Every day, even if you're meeting the worst moment in your history, say 'I just wanna be the happiest' - laugh it off; it's OK")
Daft Punk's "Something About Us", "Digital Love", "Voyager", "Veridis Quo", and "Contact" (at least until the end) are the epitome of this. In fact Daft Punk in general work on fun and good vibes to make their music.
Just about all of Eric Whitacre's choral peices are Awesome Music, but the most uplifting are surely Sleep, the hauntingly beautiful Seal Lullabye (Dreamworks picked Kung Fu Panda over this?!), and especially the upcoming various solo, orchestral, and choral settings of the beloved children's classic, Goodnight Moon.
A lot of the music for the The H.P. Lovecraft Literary Podcast is created by one of the co-host's, Chad Fifer, and his track for the story Celephais is a wonderful soundscape of bell-like melodies, soft synths and calm, lapping ocean waves.
When your jimmies are more rustled than a forest after a hurricane, sometimes you just gotta settle down and listen to some Lakmé Act 1. Click, and let the blessings of the Unrustled Triumvirate wash over you like clean, sparkling bathwater.
Normally, Silent Hill isn't a source of heartwarming, but as evidenced by the case of Letter From The Lost Days from Silent Hill 3, there is the occasional tidbit. Especially in this song about love, keeping up hope, and wanting someone else to find happiness. "Oh, what a pair, me and you, put here to feel joy, not feel blue. Sad times and bad times, see them through—soon we will know if it's for real, what we... both feel..."
Shako-Pani makes drum-n'bass inspired tunes to briefly put your troubles aside by, with sweet melodies and a light atmosphere prevalent even in his most chaotic works.
Suzuka. Her works always seem to have an air of overwhelming beauty and pure, unadulterated soul, with melodies seemingly designed to remind you that better days exist, or at least help you take your mind off the worse ones.
Suntra's "Other Victories" album. Cheesy, video-game melodies made with old equipment, bring to mind an old RPG or a sidescroller set in a cartoony, surrealist world of the sort the cover only hints at, with a warm and cheery atmosphere building throughout.
Wolfgang Amadeus Mozart, especially pieces like the Piano Concerto in G (#17), several of the piano pieces, a lot of his chamber music... The man was capable of amazing depths of happiness which cheer the very soul just by being so very happy to exist. Beethoven needed struggle against adversity, Bach was raptured in religious reassurance, but Mozart's music is just plain excited.
Mozart's SDF elements may have come from Pachelbel's works. Pachelbel sounds like an early version of modern alt music that uses SDF.
Ludo has a number of genuinely sweet, wonderful songs- I dare you to listen to Anything for You or Manta Rays without getting the warm fuzzies. There's also something delightful about the ending background lyrics of "Scream, Scream, Scream"—"All your wiser moments/All your words and closeness/Keep you here and human..."
Windham Hill's first five "A Winter's Solstice" Christmas albums are filled with sweet dreams fuel. Get a copy of "Winter's Solstice III" (you can find them on eBay for a couple of bucks). Listen to the last track, "Earth Abides" by Philip Aaberg. The simple, quiet melody can move you to tears... and sing you to sleep. Seriously.
The Staunton Lick, by Lemon Jelly. An incredibly relaxing chilled out groove with a catchy acoustic riff, sounds like the soundtrack to a nice flying dream.
In fact, almost everything by Lemon Jelly fits this. To the point of having lots of children among their fanbase.
Aphex Twin may strike you as the type that would be this trope's polar opposite, right? Not so fast: in his early career, he put out one album of ambient techno (Selected Ambient Works 85-92) and one album of purely ambient music (Selected Ambient Works Volume II). Turns out the guy behind "Come to Daddy" is also capable of stuff like "Xtal" and "Lichen."
All Saints's "Pure Shores" - a song that captures the word 'paradise' completely.
Atomic Kitten, especially "It's OK' which talks about a relationship that ended badly but they have both moved on and can still enjoy the good memories. "Whole Again", "Love Doesn't Have To Hurt" and their cover of "Eternal Flame" are nice and relaxing. And it's impossible to not want to dance along to "Be With You" and "The Tide Is High (Get The Feeling)".
Ralph Vaughan Williams was good at writing this type of music.
"The Lark Ascending". It's gently uplifting, not to mention incredibly evocative of the English countryside. Seriously, go listen to it and tell me it doesn't make you picture rolling green hills and leafy woods.
"Five Variants of Dives and Lazarus" evokes the same images and emotions.
"Fantasia on a Theme by Thomas Tallis" is a gorgeous piece of music, full of spiritual ecstasy and serene radiance.
Florence + the Machine has given the world the truly astounding All This and Heaven Too, a song that seems to sum up the ecstatic feeling of loving something for the first time. Also, there's Strangeness and Charm, which seems to emanate the basic emotion of wonder in five grand, sweeping minutes.
Lisa Loeb has the infectiously sweet hit Stay (I Missed You.) While played to the point of Glurge in 1994, it has a unique cuteness that proves a potent anti-depressant in small doses... kind of like an opiate.
Listening to "You've Got a Friend in Me" from Toy Story is an easy way to get the warm fuzzies, especially if a specific loved one comes to mind. It's just so endearing and optimistic!
An awful lot of Queen's discography qualifies, really.
"Don't Stop Me Now" is quite possibly the best pick-me-up song (and, according to Top Gear, best driving song) of all time. The energy is infectious, Freddie sells the crap out of every note, and the metaphors for the protagonist's ecstasy are over-the-top and memorable.
'The Whole Picture' by Finnish funk-rock band Funk in Funk Stairs, which encourages people to stop worrying and just enjoy their lives. Hell, the video itself could qualify: five minutes of four guys messing around in a recording studio and quite clearly having the time of their lives.
"Now the sky could be blue, I don't mind, without you it's a waste of time."
Twenty One Pilots has "Hometown", a song with choir vocals as a hook. It's very dreamy sounding, and very beautiful. Another example is "Truce", which is a slow piano song, with inspirational lyrics to tell you to keep living.
Hilarious as it is, Rick Astley's Never Gonna Give You Up, aka the Rickroll song, is actually very fun to listen to, and has excellent lyrics and a lovely beat. Plus, if you fall in love with the song, good news for you - you're now immune to Rickrolling!
Anything involving Lindsey Stirling. She dances while playing beautiful, relaxing music on a violin, often in costume, and always with a big smile on her face. Even in her behind the scenes videos, her silly antics, humility, and optimism never fail to put a smile on your face.
Jerry Nelson, one of the original Muppeteers, wrote a song called "Tides", and it's gorgeous.
Much of Alcest's music can be considered this, often veering into straight-up Dream Pop territory. "Délivrance", the final song from their latest album Shelter, may be the best and most beautiful example.
While they're no strangers to making nightmarish and/or morose material, the members of Genesis have proven several times that they can also make songs that radiate happiness.
An early example comes in the ending section of "Supper's Ready"; while the previous section was ominous, the ending sounds so victorious that it's more than enough to neutralize the previous section's Nightmare Fuel.
Later, when the band became a trio, they released "Follow You, Follow Me", an absolutely beautiful love song that can be summarized as "You make me feel safe and comfortable, and I hope you'll always be there for me".
The band members' solo careers have their fair share of this as well. Peter Gabriel, for instance, has "In Your Eyes", which is about how even though the narrator feels insecure sometimes, he still feels complete in his loved one's eyes. And meanwhile, it'd be easier to name the Phil Collins songs which aren't this to some degree - in fact, his song "Come With Me" from his album Testify originated as this, being a lullaby he would sing to his children.
Drake's song "Wednesday Night Interlude" is a few heavenly arpeggios away from being a straight Tear Jerker, it's such a beautiful track. Not only is PARTYNEXTDOOR's singing stellar (if not a bit unintelligible), but the choral harmonies in the background escalate the song from "calm" to "lush".
Christian Singer/group Plumb's album Blink will make some people feel this way.
Most of Madness' discography can count but particular mention goes to sun and the rain and simple equation both about the joy that can be found in unfortunate situation and the latter having a heartwarming "good night," at the very end from Suggs sure to make you sleep comfortably.
Rush has "The Sphere: A Kind Of Dream", the final part of the Hemispheres suite. It's a very soft, gentle piece with a inspiring message about how we can live in peace.
Also of note are "Different Strings" and the live, acoustic version of "Resist", which turns a beautiful but still distinctly heavy song into a soft acoustic ballad with just Alex Lifeson and Geddy Lee playing guitars and Lee turning in some of the most soulful and genuine vocals of his career.
Robert Rich invokes this trope with his sleep concerts, where the theory is that audience's sleep experience is affected by his music. He has even released two albums, lasting 7 and 8 hours respectively, for people to recreate the effect at home.
"Better When I'm Dancing" by Meghan Trainor from The Peanuts Movie. It's one of those songs that can make anyone feel very optimistic and be given a good feeling. Especially when you watch the music video which features the Peanuts characters.
The translation of Pop Drop Candy by Juby Phonic and Kuraiinu. It's just so happy!
Vienna Teng's "Lullabye for a Stormy Night" is all about a child being sung to a peaceful sleep and not not worry about the storm outside because their parent is there. It is a perfect song to fall asleep to to ensure some peaceful and pleasant dreams.
OMFG's music. If you've heard of him, you most likely know him for Hello. With that in mind, if you're into that kind of music, he'll be a great artist for you.
A lot of Jethro Tull's output. Hell, The Jethro Tull Christmas Album is a whole album of Sweet Dreams Fuel. But if it's individual songs you want, you could start with the three and a half minutes of loveliness that is "One Brown Mouse".
Pretty much every song by Sleeping At Last is a beautiful, calming tune about love, family, the inherent goodness of people, and the importance of every person's place in the universe. Special shoutout to "You Are Enough", which is legitimately just You Are Better Than You Think You Are: The Song.
"We're Going To Be Friends," by The White Stripes. It just perfectly sums up the magic of childhood and making new friends.
Though they arenot a band that does this normally, Sunn O))) have "Alice", an elegy to jazz legend Alice Coltrane, which starts off somewhat ominously but slowly grows brighter in tone, with the introduction of a brass section, trombones, and even harps, until it sounds completely serene and heavenly at the end. Coming at the end of the incredibly dark and heavy album Monoliths and Dimensions, it really is the musical equivalent of Earn Your Happy Ending.
This remix of Candyman that was made to celebrate the 75th anniversary of M&M's. It's just so upbeat and cheerful that it's near impossible to not smile while listening.
You may know Flying Lotus for his laidback hip hop, but it turns out he's also capable of making beautiful ambient songs like "Endless White".
"Beautiful Day" by U2. It's filled with such an endless sense of optimism, pure happiness and a love of life, that you'll probably be left appreciating life for a good while and just feeling good overall.
Don Williams is known as "The Gentle Giant" for a reason. His smooth, calm, and friendly voice can ease even the most unsettled of nerves.
Tom Smith's "A Boy And His Frog" will bring you to tears, but it will also lift your heart and spirit as few songs can. Especially uplifting is a live performance, because it's almost always followed by "Rainbow Connection," and thatnever fails to wind up with the whole audience singing along, defiantly optimistic and singing out hope and love.
Basically everything Israel Kamakawiwoʻole (aka "Bruddah IZ" or just "IZ") ever recorded could be considered this. His deep yet soothing voice combined with his soulful ukulele playing allowed him to create some of the most heartwarming songs ever performed. These include:
How is it that Yes isn't up here yet? A large part of their collection of work is pure magic, combining lovely harmonies with very gentle, loving lyrics (see: Time and A Word, And You and I, Endless Dream...) Even ones with slightly darker themes (see: Survival) can end up being this.
Most of the work by doujin circle ShibayanRecords is this, specially the Toho Bossa Nova soundtrack arrangement albums, that manage to capture a heartwarmingly melancholic atmosphere that characterizes the genre. These include:
Synthpop artist Mr. Kitty has a really soothing voice, and makes even the songs that deal with darker subject matter sound oddly pleasant. However the SDF will really come into full effect through songs that are lighthearted in both sound and lyrics, such as "Everything Will Be Alright" and "Greater Than Us".
The Go! Team. Their music is so full of playful, positive energy it'll be sure to cheer up anybody no matter how down they're feeling.
Anvil! The Story of Anvil is a movie about Canadian heavy metal band Anvil. You wouldn't expect this movie to have any music that falls under this group would you? Wrong! Towards the end of the movie the band heads to Japan after finally landing a high profile gig. Before the concert, we see a scene of the band's frontmen Lipps and Robb walking through a beautiful Japanese garden with this truly wonderful track playing over it. The fact that this scene contains no dialogue and shows Lipps and Robb just enjoying the fact that they're finally on the road to making a comeback makes it that much more powerful. The track also plays over the end credits, giving it a happy and hopeful ending. And considering how much Anvil's fortunes improved after this movie came out, the hope worked.
Tears for Fears have songs like "Head Over Heels", "Sowing the Seeds of Love", "Advice For the Young At Heart", and "Elemental", which are all rather mellow and happy-sounding, especially the former.
While it's not actually from the game but instead the anime, "We Are One and All" is a truly grand and beautiful song about friendship, hope and determination. The moment where the gospel choir joins in makes it that much more powerful.
