The normally jumpy pop rankings are quiet this week, as the only tangible change brings Garth Brooks' No Fences back to the top 10, where it has already spent several weeks coexisting with Brooks' No. 1 blockbuster, Ropin' the Wind. So this might be the time to note that Hammer's Too Legit to Quit remains a longtime, steady No. 3, even if Hammer himself has been eclipsed in the news by his nemesis, Michael Jackson. Also noteworthy are two groups without mass-market personas-Metallica, kings of metal, and Boyz II Men, sweet R&B harmonizers. They've quietly lodged themselves in the top 10 for weeks on end.
