Another "wow" for an iPhone app- ZoozBeat allows you to lay down "tracks" for different instruments- by touch, keyboard, or shake. The free version gives 2 background beats and 6 instruments; for a whopping $2.99 you get more instruments and an ability to overlay an audio track (not sure I want to do that) and to save your songs.
The cool iApps keep coming! Gesture-based portable music studio.
