Query: this guy's a bum

why do i say kravitz is a bum?: 1) very bad musicianship, he doesn't play guitar better than someone with 6 months training; 2) unoriginal compositions which "borrow" heavily from others; 3) he's a big phoney that's more interested in looking like a rock star than making good music.don't buy this stuff, you're only supporting more bad music from the record labels. and that's something none of us need.just my opinion.
