* In the very first [[WesternAnimation/{{Noveltoons}} Goodie Gremlin]] short, the gremlins sing their cheerful, happy [[http://www.youtube.com/watch?v=uYy1y8SMI7A anthem]] [[VillainSong to mayhem, war, terror and chaos and]] [[CardCarryingVillain the causing thereof]].
-->We're the gremlins, devilish gremlins\\
We're a miserable and underhanded crew\\
We delight in dirty tricks, getting people in a fix\\
There is nothing that's too mean for us to do!
* ''WesternAnimation/SouthPark'''s "Christmas Time in Hell" is a joyous song with its lyrics actually matching the tune... but it's a song that sings about how the Damned get the day off from being horribly tortured.
** In the episode "The Death Camp of Tolerance," a gerbil named Lemmiwinks is forced to [[OrificeInvasion crawl up Mr. Slave's ass]], and he (Lemmiwinks) must traverse Mr. Slave's entire digestive system and [[OrificeEvacuation crawl out the mouth]] or else he will die. Amusingly, this entire disgusting sequence is described in a song with a merry, adventure-y tune.
** ''WesternAnimation/SouthPark: Bigger, Longer & Uncut'' is built almost entirely on this trope and plays with them:
*** "Up There": A rousing Broadway showtune about loneliness and wanting to get out of a bad place. Sung by Satan. A Satan who is [[DarkIsNotEvil is not a complete monster]].
*** "La Resistance": "They'll cut your dick in half/ and serve it to a pig./ And though it hurts you'll laugh,/ and dance a dickless jig/ for that's the way it goes/ in war your shat upon/ though you die, La Resistance lives on." ''Sung by a choir of eight year olds.'' Eight year olds who usually have [=IQs=] higher than their parents but with just as questionable moral compasses.
*** "Blame Canada": A rousing march about evading personal responsibility to the extent of going to war with Canada, a country that seems to go out of its way to be America's friend. The song, however, is a satire on ''American'' tendency to scapegoat others.
** Cartman and Cthulhu's Song from ''WesternAnimation/SouthPark'' episode "Mysterion Rises". Super cheery song about, well, [[DidWeJustHaveTeaWithCthulhu being friends with Cthulhu]] and going on a rampage with him.
*** Made worse by the fact that it's a spoof of a song from "MyNeighborTotoro".
* In one episode of ''TheFlintstones'', Pebbles and Bam Bam are found singing what sounds like an upbeat, cheery song about how "Smilers never lose, and frowners never win." Do you know why frowners never win? Because THE DEVIL WILL GET YOU IF YOU FROWN.
* WesternAnimation/TheRenAndStimpyShow has the "Happy Happy Joy Joy Song". Although the song itself is a deliberately insipid -- though insanely catchy -- song about being happy, it's the increasingly insane rantings of Stinky Wizzleteats (the singer) between verses that bring some dissonance. "I told you I'd shoot, but you didn't believe me! Why didn't you believe me?!" (The reason is that most of these lines are quotes or paraphrases of BurlIves' character from TheBigCountry, but of course younger viewers -- especially kids -- can't be expected to catch the references.)
** [[GettingCrapPastTheRadar "I'll teach your grandmother to suck eggs!"]]
* One ''WesternAnimation/{{Arthur}}'' episode has Art Garfunkel act as a one-man GreekChorus to the characters' actions and feelings. This includes a part where he sings a lively song about Buster being "a sad, sad bunny." Buster then [[BreakingTheFourthWall broke the fourth wall]] and demanded Art Garfunkel sing a more melancholy version.
* The first verse of the Incredible Hulk's segment of the Grantray-Lawrence ''Marvel Superheroes'' show of the mid 1960s:
-->Doc Bruce Banner
-->Belted by gamma rays
-->Turns into the Hulk
-->Ain't he unglamour-ays?
* In the ''WesternAnimation/PhineasAndFerb'' episode "Meapless in Seattle", the [[TastesLikeDiabetes Meaps']] war song definitely counts:
-->We we we we (whee!)
-->Are going to war (We're going to war!)
-->We're going to war (We're going to war!)
-->We we we we (whee!)
-->Are going to war (We're going to war!)
-->We're going to war (We're going to war!)

-->De- de- de- de- de- de- de-
-->Destroy our enemies!
-->La- la- la- la- la- la- la-
-->Let's bring them to their knees!

-->We we we we (whee!)
-->Are going to war (We're going to war!)
-->We're going to war (We're going to war!)
-->We we we we (whee!)
-->Are going to war (We're going to war!)
-->We're going to war (We're going to war!)
** In "Norm Unleashed", Norm the Robot Man brings [[http://www.youtube.com/watch?v=_3H18bkKyG8 his own cheerful song]] about conquering the Tri-State area with an array of deadly, built-in "Weaponry".
-->If power's on your shopping list\\
Then use the elbow and the fist\\
Hum along until they get the gist\\
Just make an example of\\
Representative sample of\\
And most of them will not be missed!
** Candace sings a song called "Give Up" in "Last Train to Bustville". It's a cheerful, upbeat anthem about... [[ExactlyWhatItSaysOnTheTin giving up]]. ItMakesSenseInContext, since what she's giving up is her obsession with busting her brothers.
** "[[http://www.youtube.com/watch?v=EETGwAYoHgU Little Brothers]]" from ''WesternAnimation/PhineasAndFerb'' is sung to an extremely sweet [[SugarWiki/HeartwarmingMoments heartwarming]] tune, complete with an adorable through-the-years montage of Candace's relationship with her brothers. Then, you get to the silly chorus.
-->You will always be my little brothers,\\
Cause you're younger, we're related,\\
And you're boys.
* ''WesternAnimation/TheAdventuresOfSuperMarioBros3'' gives us "It's a Dog's Life" from "Life's Ruff". The lively and catchy song is about...Luigi and King Windbag wanting to be human again after Hip and Hop turned them into dogs.
* ''WesternAnimation/{{Futurama}}'' has a cheerful reggae song about being a bureaucrat in "How Hermes Requisitioned His Groove Back".
** To say nothing of the [[InsistentTerminology Xmas]] carol, "Santa Claus Is Gunning You Down".
* In an episode of ''WesternAnimation/TheCritic'', the national anthem of an unnamed country sounds like a repeated chant of "pee-pee, pee-pee, pee-pee, poopy", but has a [[http://www.youtube.com/watch?v=5EcaGvvhIBo rather different meaning]].
* Creator/TimBurton is a master of mixing the macabre and the lighthearted, so it's no surprise that the music in his movies are the same. The best example is "Remains Of The Day" from ''WesternAnimation/CorpseBride'', a swinging jazzy tune about death and murder. Even while you're tapping your feet to the beat, you probably don't miss the extremely dark chorus:
--> "Die, die, we all pass away, but don't wear a frown, cause it's really ok! You might try to hide, and you might try to pray, but we all end up the remains of the day!"
* "The World's Greatest Criminal Mind", from ''Disney/TheGreatMouseDetective'', is one of Disney's cheeriest villain songs. The most disturbing lyrics?
--> Even Meaner? You mean it? Worse than the widows and orphans you drowned?
* ''{{Hoodwinked}}!'' crosses it over with SoundtrackDissonance in a JustBetweenYouAndMe. After Red's fight with Boingo in the tram terminal, he orders Dolph to tie her up. She says, "You're crazy!" and he replies "Maybe, but I'm top of the woods now, baby!" So he sings "[[VillainSong Top of the Woods]]", an upbeat song with lyrics about oppression, getting children addicted to goodies, and becoming a ruthless dictator, like:

-->''"When you're hopping on down the bunny trail, the critters all seem to look down\\
You're fuzzy and small\\
Your ears are too tall\\
And goodies make the woods go round"''

-->''"Now I'm not a pig\\
But you gotta think big when you're competing with the girl in the hood\\
So you won't be a fan of my evil plan, but I'm gonna be top of the woods!"''

-->''"When your only desire is to dominate the land of the wolves and the squirrels\\
You've got to think with a open mind and learn to detest little girls\\
And everyone knows at the end of a show the villain puts his plan into words\\
Except [[MediumAwareness there won't be a rescue before the credits roll]] cause I'm gonna be top of the woods!"''

-->''"Now the kids will be packed with my [=BoingoSnax=]\\
Construction begins in a day\\
And all of the bears will be ruled by the hare\\
As I maniacally plot from my evil lair!"'' [''cue [[EvilLaugh evil laugh]]'']

** At the end, with some nice upbeat chords: "[[TitleDrop You've been hoodwinked, baby!]] Oh, yeahhh"

** The soundtrack dissonance comes when you consider his audience (Red, who is tied up with ropes).
** After the song ends:
-->'''Granny Puckett:''' Sweet tea and cookies! We've got to do something!
-->'''The Wolf:''' I know. [[ComicallyMissingThePoint The song was catchy, but the choreography was terrible.]]
* The Island of Misfit Toys segment from ''WesternAnimation/RudolphTheRedNosedReindeer'' starts with a song about the toys being unloved and missing out on the joys of Christmas, when the song itself sounds very cheerful.
* [[http://au.youtube.com/watch?v=imKPenpVyPQ "L'il Ark Angel"]] from ''WesternAnimation/CatsDontDance'' starts with Darla singing about the world being destroyed in a flood and people and animals drowning in exactly the same cheerful tone she later sings about the various animals she's rescuing. If you hadn't already realized she'd be the BigBad of the film from the foreshadowing in the intro, it's hard to miss it after that.
* Some of the [[WesternAnimation/VeggieTales Silly Songs With Larry]] invoke this. From an 80s love ballad...about cheeseburgers to a tango...about manatees, the team purposely make the music sound completely authentic to the genre while keeping the silly lyrics.
* A cutaway scene from ''WesternAnimation/FamilyGuy'' features [[http://www.hulu.com/watch/5547/family-guy-you-have-aids "You Have AIDS,"]] a happy barbershop quartet song that Peter sings to [[ExactlyWhatItSaysOnTheTin someone who has contracted AIDS]].
** In the episode "Welcome Back, Carter", Peter sings a song to a soft romantic tune to "set the mood". Unfortunately, he chooses his favorite song, "Surfin' Bird".
* Another example from a cartoon, namely ''WesternAnimation/DrawnTogether'', is Foxxy Love's touching ballad [[GrotesqueCute "Crashy Smashy Die Die Die."]]
* [[http://www.youtube.com/watch?v=LXSsagwvo3M "Batty Rap"]] from ''WesternAnimation/FernGullyTheLastRainforest''. It has a fast and springy beat and tune.....with the lyrics being about how Batty was used in animal testing laboratory, with strong implications that ''he was conscious throughout all the processes''. Due to its 'adult' nature, quite a bit of the song was cut from the film, but was [[http://www.youtube.com/watch?v=x1g5Oajn5UE left in on the CD]].
-->"The Eye makeup, when inserted rectally, has some effect...
-->Remove the brain cap...
-->If you notice, by dipping the bat in a series of paints...
-->After 600 packs of cigarettes, the animals seem to exhibit some carcinogenic tendencies..."
-->[[GettingCrapPastTheRadar Oh God, I'm bleeding by my genitals!]]
** The tune's single most horrifying line: "As you see, the animals don't really feel pain, ''THEY JUST GET USED TO IT!!!''"
* As an example from a musical - ''Disney/TheLionKing 2'' has [[http://www.youtube.com/watch?v=yJGqxf86cZs "My Lullaby"]], [[VillainSong a brutal declaration of war and violence]] set to the tune of a children's lullaby. On the other hand, it grows to be pretty creepy...
* The children's movie ''WesternAnimation/TheBraveLittleToaster'' contains a song near its end which the other wiki sums up perfectly: "''Worthless'' is sung by the junkyard's broken down cars, each singing a few verses about their life before being smashed and killed by the compactor." However, they fail to mention the upbeat music it's sung to.
* "Christmastime Is Here" from ''WesternAnimation/ACharlieBrownChristmas''. It has lyrics that describe how wonderful Christmas is ("Fun for all that children call their favorite time of year") but has a very slow, almost melancholy feel to it. This makes it memorable.
* "Won't You Come over to My House?", best known from the famous short ''OneFroggyEvening''. If your memory's a bit hazy, [[http://www.youtube.com/watch?v=DqB_YYB8TJU here's]] the cartoon, and [[http://froggyeve.tripod.com/comeover.html here]] are the full lyrics.
* This is pretty much the entire gimmick of Dethklok on ''WesternAnimation/{{Metalocalypse}}'', as they render ''everything'', from the blues to a jingle for a coffee shop to a birthday song, as over-the-top death metal.
* The song "The Violin", by Brian Dewan, is included on the album ''Where In The World Is Carmen Sandiego?,'' notably a [[WesternAnimation/WhereInTheWorldIsCarmenSandiego kid's show]]. It is set to decidedly upbeat, Irish-sounding music. The song's lyrics discuss a kid who is constantly trying to break away from his controlling parents' desire to make him learn the violin, getting snubbed by his crush for someone who ''does'', and then ultimately drowning in a shipwreck. It's a children's album, fun for the whole family!
** The titular song by Rockapella could qualify, as a peppy upbeat number about an impossible-to-catch criminal and her various misdeeds.
* Music by Jody Gray are great examples of this trope. Both ''[[WesternAnimation/{{Arthur}} Arthur's Missing Pal]]'' and ''[[WesternAnimation/CliffordTheBigRedDog Clifford's Really Big Movie]]'' feature upbeat music... with downer lyrics about the protagonist's lost dog?!? In the latter, the opposite also occurs on a tribute CD: the owner of said big red dog sings upbeat lyrics about her dog to a bitter-sounding tune.
* The song "Mother Knows Best" in ''Disney/{{Tangled}}'' is a cheerful, bouncy song where Gothel terrifies Rapunzel by listing off all the "scary and dangerous" things in the outside world and how all of them ''will'' happen to Rapunzel if she steps out of the tower. Throughout the song, Gothel is intentionally [[AbusiveParents emotionally abusing]] Rapunzel by playing with her fears to make her seem like she's the only one in the cruel world Rapunzel could trust.
-->If we're on the island of unwanted toys, we'll miss all the fun with the girls and the boys...
* [[http://www.youtube.com/watch?v=aN6ef0ED9aI "The Ballad of Magellan"]] from ''WesternAnimation/{{Animaniacs}}'', a rather lively and happy-sounding song about Magellan's famous voyage - the one that ended in his death. The song is ''far'' more lively than the lyrics, tune, and story (which is actually historically accurate) suggest.
* In the ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' episode "Winter Wrap Up", the cast begin singing a jolly song about [[PaintingTheFrostOnWindows cleaning up winter to make way for spring]]. Rainbow Dash sings about awesome holidays, Pinkie about having fun and Rarity about fashion. Applejack? She's singing about possible starvation due to running out of food.
--> '''Rainbow Dash''': Three months of winter coolness, and awesome holidays
--> '''Pinkie Pie''': We've kept our hoovsies warm at home, time off from work to play
--> '''Applejack''': But the food we've stored is runnin' out, and we can't grow in this cold
--> '''Rarity''': And even though I love my boots, this fashion's getting old...
* In "The Singin' Kid" on ''WesternAnimation/PBAndJOtter'', there's Jelly Otter singing about friends and family keep her strong and being true to herself at the same time she lets fame go to her head in "The Singin' Kid."
* "Let It Go" from ''{{Disney/Frozen}}'', an uplifting-sounding song by Elsa about finally accepting her powers...which is also about choosing to live a life in isolation and cut herself off from the world.
