A Global Army of Veteran Rockers
Allow me to speak from ignorance with regard to rolling.fm or turntable.fm
From my limited (so far) understanding of how it works (a lot of my buds are using it, I'm only getting around to it now..) I would bet that Spotify is the way to go.
The free version.
We all get on it, and then just email each other (or just post them here, for example) the playlists, libraries, etc, that we make up, recommend, etc, and then it's all in everybody's library.
This coming from the world's foremost Rhapsody proponent.....I don't see how anything can surpass Rhapsody....imho oxygen and food are among the things that are less valuable than Rhapsody...but I have to admit...it's not FREE
I've tried Spotify but haven't spent enough time to make it work, still trundling along on last.fm. If youse guys are out there, on Rolling or Spotify or whatever...I'm down with it.
