fun music creating software?

[fustercluck]

Was just thinking the last fun music creating program I used was Mario Paint. Which is hard to beat, let's face it. Thought I'd see if there was any fun music creating software out there? It'd have to be pretty dumbed down, nothing that requires a 300 page manual. Just wondering. Can always go back to Mario paint! Thanks

Fl Studio (or Fruity Loops) is really nice. I use the producer edition for doing electronic music.
I also like Ableton Live a lot.

You can check demos here:

Not exactly what you're looking for, but PaulStretch is fun for modifying existing songs. It stretches out songs, and changes the character. It makes ambient tracks out of anything.
