Ok, so I may be a little bit behind the times, but I just discovered Pandora. This web site is based on the Music Genome Project and allows you to create up to 100 radio stations based on your favorite artists or songs. You input your favorite artist or song and they build a radio station around that artist or song based on a number of algorithms that they have. The stations are pretty accurate and allow you to discover a lot of new music. The basic ad-supported version is free, but you can also buy a membership with no ads. They also have some restrictions on how you can play the music based on the streaming music license they have. All-in-all it’s a great product and an excellent way to discover new music.
