I love Pandora
I've been introduced to a lot of good music I want to buy, but can't find (and can't afford all at once).
Including: Nightwish, Xandria, Lacuna Coil, Plumb (maybe), Within Temptation, and Leaves' Eyes.
Yes, there is a trend here. >_>
I got all this stuff by tell Pandora I liked Evanescence. Also, I've changed my mind about Flyleaf. I hate "I'm So Sick," but I like everything else I've heard from them.
