Anita Baker continues to defy doomsday predictions with her very jazzy "Compositions" album. Some said her pop fans wouldn't like its jazz orientation, which would cut down on pop sales. But so far, the album has been selling very well. It moved up a notch to No. 5 on the Billboard magazine chart, without the aid of a hit pop single. 2 Live Crew's controversial rap album, "Banned in the U.S.A," is big in the U.S.A.--bolting up to No. 21 in just three weeks. Hot new metal albums: Winger's "In the Heart of the Young" (No. 15) and Vixen's "Rev It up" (No. 54). Mariah Carey's "Vision of Love" is the No. 1 pop single for the fourth straight week.
