JANET JACKSON: ''All for You'' (Virgin). Girl beds guy, girl dumps guy, girl moves on: that's the story line for Janet Jackson's post-divorce album, ''All for You.'' Fans of celebrity gossip can savor ''Truth'' as Ms. Jackson reminds her ex, ''I had a career before now/I sold out 'round the world before now.'' While other songs portray stock situations, Ms. Jackson and her longtime producers, James Harris III (Jimmy Jam) and Terry Lewis, approach them in songs so baroquely sumptuous that they're virtually experimental.
''All for You'' isn't as immediately melodic as Ms. Jackson's previous albums, but it compensates for lost catchiness with unabashed strangeness. An addled-sounding Carly Simon semi-raps through a song loosely based on ''You're So Vain''; a gamelan sample peals through ''China Love'' (and Ms. Jackson doesn't care that gamelans are Indonesian).
Boudoir ballads undulate in torrid slow motion while Ms. Jackson moans like a phone-sex operator, and uptempo tunes hark back to disco, splice mock-operetta to hard rock or, in ''Better Days,'' conjure an easy-listening 1960's-pop apotheosis. Countless overdubs of Ms. Jackson's voice turn her into an airborne choir; computer rhythms thump and sizzle. As other rhythm and blues strips down to match the angularity of hip-hop, Ms. Jackson luxuriates in textures as dizzying as a new infatuation. JON PARELES
