I voted for Last.fm. It's easy to use, can be used in WinAmp, Foobar2000 and a few other apps. They have their own API, which Pandora does not, and that is easy to use as well.
I have tried Pandora, but I also don't like the limited skips. I just looked up the limit, and it's 6 per hour, per station, whether you're using a free account or paid one. If you use a free account, it's 12 per day. That's pretty weak in my opinion.
Also, thanks PuRelite, I'm using Jango right now, and so far I like it.
One more note: This is my first post on x10, soooo... HI! :wavey:
