Every single song in the entirety of all of the games, to an extent. Some of them can even be manipulated to change which track components get played. And they just keep adding more via DLC.
In LBP2 and later games, you can create your own songs with the Music Sequencer, which has resulted in level creators composing utterly AWESOME tunes. Players who really know what they're doing can even compose their own music in LBP1 with Music Note Objects and a few (hundred) Magnetic Keys.
LittleBigPlanet 1
- Despite it being licensed music not specifically composed for the game, "Atlas" by Battles ended up becoming synonymous with the series as its Signature Song, due to how its unconventional Math Rock composition perfectly encapsulates the essence of LittleBigPlanet's chaotic sense of fun.
- "Get It Together" by The Go! Team is used prominently in the first game and is practically synonymous with the game series.
- "Volver a Comenzar" by Café Tacvba, used in the Dia de los Muertos themed levels in The Wedding, is as catchy as it is melancholy and helps set the tone for Frida the Bride's story levels.
- Boom Town is definitely That One Level, but at least it comes with a great song. Whether you take the time to Ace it or not, Cornman will undoubtedly get stuck in your head.
- "Song 2" by Instrumental Hip Hop artist DJ Krush is a remarkably solemn lo-fi track that makes Sensei's Lost Castle all the more atmospheric. Don't be ashamed if you feel a bit weepy on repeat listens.
- The Gardens Theme, the song so nice they remixed it twice.
- What plays for the final battle with The Collector? A piece of Sergei Prokofiev's score for Alexander Nevsky!
LittleBigPlanet 2
- The music for the LBP 2 announcement trailer, "Sleepyhead" by Passion Pit. Though, they didn't use the entire song, they just used the part that most people know, the 'Fairy Chanting' bits that are really only in parts of that song. Did you even know it had lyrics? "Sleepyhead" is also used during the credits.
- The second game's Pod music just has an atmosphere of joy and wonder to it, that seems to make hanging out in the Pod a bit more fun.
- The instrumental version of "Whoever Brings the Night" by Nightwish is used for the first and fourth boss fights and it makes a fight against a monkey armed with yoyos feel incredible.
- "Vision One" by Royksopp. The instrumental version in the game is pretty awesome, but the original version actually has cold and depressing lyrics to accommodate it.
- If you like drum and bass, then you'll want to hear this masterpiece, "Planetarium" by Squarepusher, in LBP2.
- LittleBigPlanet 2 has funk remixes of Also sprach Zarathustra (here) and Beethoven's Fifth Symphony.
- The song that was used during the final boss battle against the Negativitron really adds to the scene. It's the finale from The Gadfly Suite.
- Da Vinci Tutorial IntMusic, the period instrument-filled piece from "Rookie Test".
- "Victoria's Laboratory" includes instruments typical of a polka, beatboxing, a rock concert, a violin concerto, an opera, and a trio of ladies singing in the shower. Then it all comes together into a seamless song.
- "I Have Changed" by HP Riot, an awesome soul/R&B track that plays in the Factory of a Better Tomorrow.
- "Ghosts" by Ladytron is a beautifully haunting track that plays over the credits.
- "The Future", which plays during the ending, is a mix of Awesome, Tear Jerker, and Heartwarming, all in one orchestral and beautiful track.
- The Muppets Level Pack brings Deep Space Sonata, an extremely funky track.
LittleBigPlanet 3
- The "Garden Theme" makes another appearance in 3, as an a cappella version sung by none other than Internet favorite and bearded cat enthusiast Smooth McGroove.
- There's an instrumental remix of "How You Like Me Now" from The Heavy in the third game too. It's used during a brief segment in "High Stakes Heist" during which you do some quick platforming while the floor is exploding under you.
- The aptly superhero-esque "Hero Theme" from the third game makes the final boss about 90% more epic.
- The third game delivers rather excellently when it comes to music. Things like the blissful "Race Against the Sunset" and the dramatic chase theme "Vitium In Opere" come to mind.
- All of the "retro" music from Manglewood ("I Only Have Eyes For You", "Pink Shoelaces", "Mr. Sandman", and "So Fine") is pretty great and ear wormy. No wonder Marlon thought they were catchy.
- The amazingly uplifting and positive "Energy" plays over the end credits.
LittleBigPlanet PSP
- "Neopolitan Dreams by Lisa Mitchell is a relaxing track with calming vocals and lyrics.
- "Glockenpop" by Spiderbait essentially became to this game what "Get it Together" was to the first one: a hyper infectious Signature Song that sticks with you long after it ends, with lyrical commentary on the complacency of pop music to boot.
LittleBigPlanet Karting
- "Grand Theft Ecstasy by Feed Me is a catchy, high-energy EDM track.
Sackboy: A Big Adventure
- The reveal trailer features another hit, "Mayday", from the fan-favorite band The Go! Team of LBP1 fame with clever use of Morse code, pounding drums, boisterous brass section, and catchy-as-all-hell vocals.
- The surf rock remix of the song Take On Me by A-ha makes the otherwise frustrating co-op level "Squid Goals" feel like a fun jaunt on a California boardwalk pier.
- Imagine you're playing through "Bubble Jeopardy" for the first time. You're enjoying the catchy whimsical ballet music playing in the background, but wow, that melody sounds familiar. Then, halfway through the level, it immediately dawns on you that you're listening to a remix of "Material Girl" by Madonna.
