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.
- "Get It Together" by The Go! Team is used prominently in the first game and is practically synonymous with the game series.
- 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.
- 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!
- 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.
- "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.
- "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.
- 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.
