I bought the one-time purchase version, which gives you 3 free songs each month. In the menu, you choose Update Songs.
Sad to say, after playing the game several times, I couldn't bear it anymore. Incomplete MIDI versions of songs and crappy, iffy controls make this game completely unworth the purchase. I deleted it.
This game is pretty cool, a lot better than I thought it would be. Luckily they were giving away 1000 free copies on the UK BB Owners Lounge. I've almost got it beat.
