Here is short overview of the music that is likely to be in LittleBigPlanet 2. Note that not all of the songs have been officially confirmed and that there might be some changes before the release of the game.
Also Sprach Zarathustra by Deodato. This jazzy remix of Richard Strauss’ was confirmed in the preview article in EDGE
A Fifth of Beethoven by Walter Murphy. This disco version of the Beethoven classic can be seen in this screenshot.
Infotain Me by Ochre. This has been accidentally confirmed by Ochre himself on his Twitter feed.
And last but not least the song that was used in the trailer. We do not know whether this song will actually be in the game.
Sleepyhead by Passion Pit
Since LittleBigPlanet 2 will most likely be completely backwards compatible it is also save to assume that all the songs from LittleBigPlanet will be back and we don’t doubt there will be more new tracks than just those four. Once we find out more we will let you know.
