Mashable has a nice roundup of over 30 web-based music streaming sites. I’m sure you’ve heard of Pandora, but did you know there are at least 4 other similar ‘music discovery’ sites? Or what about the few dozen streaming sites like Last.FM, iLike, or Live365? Damn you Mashable – now I have to spend lots of time exploring these! 😉
