I recently discovered that Radio 3 has evolved considerably and now offers proper streams, as well as bunch of dandy new features. I'm most interested in the user playlists, I may make one up there myself. The whole concept of the site is very progressive. (and is one of the rare sites that use flash very effectively)

I guess there is a Francophone counterpart at
http://www.bandeapart.fm/ but it appears to be all flash IE only.
