Heavier Things is a pretty good album. It isn't, however, a kids album. There really isn't anything wrong with it, but I don't think the slow balads and vintage guitar solos could hold a kids attention for more than five minutes. But if you're a mellow, poem-writing teenager, this one is for you.
I got the DualDisc edition and I was HOOKED on it! Mayer's vocals are beautiful and the album's awesome. There's no profanity besides a couple of "d*mn"s on "Bigger Than My Body". Otherwise it's gorgeous poetry.
