This might be ancient news but it was new to me when I noticed it the other day. I'm not sure if this was noted in the beta 2.0, but now you can stream your music from your phone over bridge. Just go to your phone's music folder on the File Manager app, pick a song, and hit open. Oddly enough, it opens in the video player (but videos will not play over bridge).
The problem is (other than the unattractiveness of playing in the video player), it just plays that one song, and that's it. You have to keep selecting songs in File Manager. Not a fun way to go.
