 Pandora Internet Radio
I was just told about Pandora by a friend today and I decided to check it out. You put in the name of an artist or song that you like and Pandora will create a "radio station" that plays music that has similar sounds to the artist or song. It's also free (subscribers don't get any extras other than no ads), which is nice. I've been playing it for a while and I picked up the names of a few good artists that I didn't know about before. Definitely worth a look with a lot of different features and things to check out. |
