musicap

that domain is taken, but it is the best to describe this idea..

a music player that replaces the cap for your flash stick.

maybe that exists already? i don't know why not. it cost about $2 in parts to make a player. the expensive part is the ram. the nice thing about this idea is that if you want some giant-ass 4gb stick.. good for you. if you want to have 10 128mb sticks. good for you.
