When playing from a particular playlist, RB currently  disables the
browser. In my use of RB, it would be really nice to be able to use the
browser while viewing a playlist.

One of my big uses of RB is to play music in an office. The other is to
play music at home. Both have distinct sets of rules defining
appropriateness :)

If the browser could still be used to navigate the subset of content that
I've loaded from the playlist, it would allow me and my co-workers to
select music from a pre-approved list of what's okay to play in public.
