I'm using vista and the only way to add track is via the mass storage option however if i put more than 15 albums across it runs super slow while playing them I dont suppose you see the same problem with yours?
So far I'm just getting used to it, I choose this phone as I already have a HTC TyTn and wanted somthing a bit less cumbersome pocket wise, I love the look however I find the UI less responsive than what I expected than other phones I've used. The phone seems to crash and show flashes of different colors if i use it for extended periods of time IE listening to music for hours and then hammering it with calls and texts a simple soft reset and time to cool down quickly fixes it (This may just be mine though). Overall the only gripes I have can be fixed with a software update and mabye a replacment vista compatibility would be a nice addition too.
