When I see bitTunes I think spittoons. May be just me.
I don't know how to insert the greek letter mu but I was thinking
BitShares uTune "mu Tune" (pronounced myoo) as in micro
kind of plays on iTunes, YouTube and [m]uTorrent
indicates they're your tunes as well as keying on the micro transactions that are possible, as well as relating it to decentralized torrents.
IDK still comes back to bitTunes or worse bitutunes.
