This is the disc that brought McFerrin to a deservedly wider audience. As such, it has broader, but to these ears, shallower appeal than a couple of albums that preceded it and his more adventurous work to follow.
I wonder if "A music fan from NY" bothered to listen to the whole album. "Don't Worry, Be Happy" is the first cut and easily disposed of. In the right mood, or to certain listeners, it can hit the spot, but it's easily the least interesting tune on the album (save, perhaps, for "Come to Me"). I suspect McFerrin himself shares "music fan"'s low opinion of the piece: I have seen him live in concert eight times and he has never once sung that song. That's probably why he released it to a rental car company for their TV ads.
There are several fabulous cuts that more than make up for the hit single. "Drive," which is probably just cool on disc, is amazing when McFerrin riffs on it live. Most of the cover tunes are pretty arresting, especially McFerrin's vocal rendition of a screaming lead guitar on "Sunshine Of Your Love," but probably don't wear that well over time. I've always liked Creedence's "Suzie Q," so McFerrin's version, with a spooky bass rhythm/harmony line, still gets me. And yet another Beatles cover (there's one on each of the two preceding albums) done well.
