Internet radio opens a Pandora's box

I've been spending a lot of time listening to Pandora lately, and I like what I hear.

Pandora is the best new thing in internet radio, a service that, once configured properly, will deliver you a constant stream of music you will actually like. Since I've started using Pandora, commercial radio hasn't had a look-in and even my newly acquired iPod sits unused as Pandora plays.

There are thousands of internet radio stations that let you customise play lists. Most of them are free and provide music in very good audio quality. But none have the intelligence of Pandora.
