Well, I've finished listening to the Fort Minor CD. It's not bad. It's nice in that the topics of the tracks are somewhat less cliché than a typical rap CD. A rap about Japanese internment is a welcome touch. Mike is a decent rapper, and the album is extremely well-produced.
I don't normally listen to rap when I'm working because it becomes distracting after a while, but I made an exception for a gift.
You can definitely make the connection to Linkin Park; it's all depressed and in a minor key. The lyrics could be from Linkin Park songs too. They're okay... they're nothing special, but "okay" is fine for rap, I suppose. Basically, it's just Linkin Park without Chester singing and without guitars.
