I'm kind of interested in trying Sirius radio: apparently you can get 3 days for free. Have you tried it? How is it?

I've also recently came across Pandora.com, where you can put the name of your favorite artist or song, and it will play similar music: great for discovering new artists, and listening to more music of the kind you like... I liked that.

My boyfriend has it in 2 of his 3 vehicles and I had just their music stations with Dish Network until I downgraded packages. They're decent and I wouldn't mind having them in my car.

Did you hear about Last.FM? :D

IDK about satellite radio - i use my ipod everywhere i go.

Oh, so that's what Last.FM is? Hmm, I just went there and it's not very intuitive how to use it. On Pandora.com I can just sit back and listen ;)

Well there's a "Listen" tab as well as big button on the first page. The cool thing about Last.FM - it can monitor what you are playing on your PC/mp3 player more often and give recommendation.

I got it free in my car for a year (which expires this december).

It's awesome. I love the 60s 70s and 80s stations and listening to Howard Stern on the way to to work. :)

I'm going to renew it for the length of the lease of my car.
