TLC gave little indication back in '92 that their girl-powered blend of hip-hop and R&B would define urban radio for the next decade. In the absence of scorching pipes, T-Boz, Left Eye, and Chilli pumped sass-itude into some of the catchiest hooks of a generation. From the cheating parable ''Creep'' to the loser lament ''No Scrubs,'' their best work still bubbles with the pride of independent women. Call them Destiny's Mama.
