first off, this is amazing, it actually streams the music better than my itunes plays it, i have so many songs, my itunes tends to skip especially if my memory is running low, but this--not this, its great.
anyway, one thing i would recommend in a future release would be the opportunity to scrobble songs to your last.fm profile, my itunes is hooked up, but since ill be streaming them from pulptunes, it wont.
i have an iphone app similar to this, it streams my entire itunes library and playlists on my phone through 3g/wifi, its called "simplify music", it has last.fm scrobbling so I think it's possible, not sure.
just a consideration, thanks again for this wonderful program!
