Another option that works pretty well for streaming music from your PC to your TP2, is Didiom. It will even play your itunes songs, if you're into that. It responds very quickly, as if the music is right there on your phone! I have been an Alpha and Beta tester since first release and it keeps getting better!
DIDIOM Description:
Listen to songs, podcasts, and audiobooks from your iTunes® library, right on your phone.
With Didiom, you can use your BlackBerry® or Windows Mobile® phone to access music, podcasts and audiobooks stored on your computer, through wireless streaming. Just download Didiom Desktop and Didiom Mobile, choose the folders where you store your audio files and playlists on Didiom Desktop, and make sure your PC and phone are connected to the Internet. You’ll be surprised how quickly your library shows up on your phone. Then, when you add new audio files to your computer, Didiom Desktop automatically scans them and makes them available for wireless streaming on your phone.
Discover new music anywhere, and download to your phone and PC.
