Pandora is a music discovery service designed to help you find and enjoy music that you’ll love. It’s powered by the Music Genome Project, the most comprehensive analysis of music ever undertaken. Just tell us one of your favorite songs or artists and we’ll launch a streaming station to explore that part of the music universe.
I’ve been trying it out this morning, and I’m pretty impressed so far. The stream is a reasonable quality (128kbps) and the songs picked have been pretty accurate so far. Best of all, it’s free. I guess they plan to pay for the music licensing by selling ads for free account users. If you purchase a paid membership, you can ditch the ads for $36/year.
