I’m sure most people have one or at least heard of it, but Pandora Internet Radio is a pretty cool place for music fans. It requires you to make an account but it just asks for your email – no big deal. Also, once you sign in you’re signed in for life (that’s how it works for me anyhow). Basically you create your own stations by selecting an artist or song you like then it will keep playing that artist as well as similar ones. When a song plays you can thumbs up or down it. If you thumbs up it’ll be played again, and thumbs down it’s gone. If you get sick of a particular song (if you thumbs up one they tend to play it A LOT) you can put it “on the shelf” and it won’t be played for the next 30 days. You can make as many stations as you want and they have a quick mix station where it’ll play randoms from the stations you’ve already created. I’ve found a lot of great bands through this system. One annoying thing is that in one hour you can only skip seven songs due to some sort of legal business. For all you iPhone/iPod users – there’s a free app for this as well.
