The lowdown on some of the class of the idol rich: * Backstreet Boys: The studly quintet is up for a best new artist Grammy and is the 1990s New Kids on the Block--except this group can really sing. The look: Suburban kids wear urban clothes and strike dour poses. The sound: R&B lite. The bottom line: Their debut album was the third-best seller of 1998, and the follow-up is due in April.
