Ah, got it now. For some reason, I had to activate Services AND restart MB before it showed up (had already restarted MB a few times, but not while Services was active). Working great now!
Running comments:
*I can't paste a URL into the browser with Ctrl+V, for some reason (but I can right click and paste)
*Would like to be able to make the MP3 list at the bottom bigger.
*Would like to be able to scroll with the mouse wheel
*MB's forward/back buttons don't always work correctly when trying to return to the browser from another node
*The browser forgets its history if you accidentally move to another node. It also reloads the page every time you leave and return, when it seems like it could be cached.
