Pandora is a free internet radio station which "streams" songs to your internet browser. This means you can't download the music - you can only listen to it via Pandora. So all you anti-downloading activists out there can calm down before you burst a blood vessel.

What makes Pandora really good is that you can set up your own personal radio station and then you can specify what music you like to listen to. Pandora will then play you other music which it thinks is similar to your tastes. You can rate each song to tell Pandora whether you liked it or not. The site will then use your positive / negative ratings to tailor your future music playlist. So eventually it learns what you like to listen to and not listen to. If you really don't like the song currently playing, you can skip to the next song, just like you would on a CD player.

The sound quality is excellent and there's even a link to buy the song on iTunes if you like it enough to pay for it.

The site has already got me interested in Billy Idol and Def Leppard, both of which I am currently looking at on iTunes.

So if you're stuck for new music to listen to, I recommend you give Pandora a try. The only downside is that due to Pandora's music licence, you can only skip past 5 songs a hour. After that, you have to listen to the song whether you like it or not.
