I've spent ages just scratching the surface of this list. There's obviously a lot of not so good stuff to wade through here, but I've found IMHO a few cracking sites.
One in particular I'm listening to at the moment is Deezer. I've just set myself up a playlist of Springsteen songs, including his latest album "Magic", and the playback quality is excellent. This was definitely worth registering for free.
This is an interesting site if this REPORT is anything to go by, and some of you guys may already know it, or know it by its previous name.
You guys will probably work this out for yourselves, but I found that you have to right click on a song to play it. For some reason left clicking doesn't do it.
