I would love to see last.fm support for windows users. I love my soundbridge and I love firefly, but I really, really miss last.fm….
Have you seen sbPopper?
Runs in windows and “watches” your Soundbridge for what’s playing to Scrobble it. Disadvantage is you have to keep Windows and Last.FM running for it to work, but guessing you keep Win running anyway if you run Firefly on Windows.
