Here’s an idea with lots of jollies per dollar: Pandora Internet radio. The idea is pretty much like a radio station: music plays with only a few commercials. Where Pandora excels is in figuring out, automatically, what you’d like to hear. You start by giving it the name of a favorite artist or song, with some basic information about yourself. Pandora then picks music you would like. You can vote to “like” a song, in which case Pandora will play additional similar songs for you. Or you can vote to “unlike” a song and Pandora will move on to another one. As you vote on more songs, Pandora gets even better at figuring out what you like. Try it out at www.pandora.com . Oh, did I mention it’s free?
