Very impressed with Poweramp app, works perfectly so far on HTC Desire, in particular love the EQ functionality. One thing needed to perfect it though, is adding shuffle by album/folder. As an ex ipod user this is one thing I really miss, my ipod used to surprise me sometimes, and I now don't want to have to choose what album I listen to every time. Unless I'm missing something as far as I can see Poweramp always shuffles by song, wherever I start shuffle from. If you could replicate that ipod functionality allowing choice of playlist combined with shuffle by album (or song if thats your preference) then it would be complete IMO.
