Sweet Android Music App

If you are an android user and don't love the stock music app you could go to the market and look for an alternative (there are many).  However if you liked the way windows phone 7 made theirs look you might want to check out alpha build of Fede's Music app.

It's pretty slick, and as far as I can tell stable.  I mostly stream music though so I don't play music off my card everyday (that would require me to actually buy some music).  If listening local is your gig, then check it out.
