Nine Inch Nails' new one, With Teeth, is excellent. I've been a fan of theirs since The Downward Spiral, so perhaps it's not surprising I like it, but it's been pulling good reviews from everywhere. I've played it over and over in the car and the wife even likes/doesn't mind it - which is an accomplishment, since earlier albums of theirs gave her a headache. To her dismay, I think our son got my music genes - he loves it as well.
I've also become addicted to System of a Down's "B.Y.O.B." I love the rhythm changes and the guitars are great. It sounds sorta like what Frank Zappa may have written if he had been in a heavy metal band. I think I'll start getting their albums.
