I first knew about internet radio by listening to Soma FM back in 2001 or 2002. It was pretty cool by then.
Lately I’ve been using Last FM quite a lot. I find it quite nice the way they have everything set up. They have a nice mp3 player with which you can listen to the music they are constantly streaming. Not only that, you can listen to different kinds of music at any time, searching it by artists or by music tags. It’s also a social website where you can see what your friends have been listening to lately or even get recommendations based on the music you’ve been listening to.
Anyway, I believe that it is pretty cool and I’ve just subscribed for 6 months so I can test it, but primarily to support them. Keep on with the good work :-)
