Proof that, in the '90s, negative publicity about drug use and harsh, ''unreleasable'' albums makes no difference to the fans: Nirvana gives birth to a hit as its fourth album, In Utero, enters the pop-album chart at No. 1. (The group's appearance on the season premiere of Saturday Night Live on Sept. 25 couldn't have hurt.) Proof that the '80s are over: John Mellencamp's Human Wheels slithers out of the top 10 after a mere two weeks. (Maybe he should bring back ''Cougar.'') Proof that the '70s aren't over: Meat Loaf's improbable hit, Bat Out of Hell II: Back Into Hell, hangs tough, dropping only one notch to No. 4.
