Awesome work, definitely keep going at it. This is an overlooked aspect of UX and you could write a lot about how to use sound effectively in an app.

At rapt.fm I would spend time hunting for the right sound, it was often really hard and rewarding. Sometimes I ended up using effects seemingly unrelated the intended action, but in a humorous way (for example, a smack sound for challenging people to rap battles).

A lot of thought has to go into sound design. Games have done it for years but with phone, pad, and real-time web apps it is becoming crucial.
