Blip.fm and Twitter already play together fine. If you hook up your accounts, when you blip a song, it twits it in your twitter streams. Now, if you click on the provided link, it opens a browser for blip.fm I'd prefer to just add blip.fm as a service to twirl, and if I click on a link in twirl, it opens up in twirl. Or even if I have a second window opened to my blip.fm stream, then I can follow that line.
