One of my newest addictions has got to be Pandora. Pandora is a simple program that does a very complex thing. All you need to do is pick a genre/song/artist or something similar in terms of music.
It then creates a radio station based off of that search critera for you to listen to. All you need to do is listen to periodic ads. The best part is that you can use this on the Web, on your PC, even on your smart phone. All you need a internet connection to stream it.
The best way to become boring is to say everything.
