To unlock the songs, you can simply play through the game and they should be revealed over time.

If you just want access to them ... go to the "Extras" Menu, choose Modify game and input this code:
Red, Yellow, Blue, Red, Red, Blue, Blue, Red, Yellow, Blue

Done right, you'll get a notice that you unlocked all the songs.
