The Music Genome Project's Pandora Radio is an awesome version of internet radio. First you're asked to input your favorite song or artist. Pandora then creates a personalized station that offers up music that shares similar qualities to your selection, like rhythm and melody.
For example, if you choose Amy Winehouse, your radio station will be made up of songs by Amy, Alicia Keys and Joss Stone, as well as lesser known artists, some that haven't even been signed to record labels yet. In fact, Pandora is a great way to learn of new music you might never otherwise known about!
The best part is that all the songs are free, and you're allowed to create as many stations as you like. Visit pandora.com and let us know what you think!
