The New Kids' comeback album contains songs like "Grown Man," "Big Girl Now" and "Put It on My Tab," designed to deliver the message that they're no longer the fresh-faced tweens on your pre-algebra notebook. But when one of them sings, "Let's try every position," on "Sexify My Love," it's hard not to smirkify your face. Sure, the New Kids deserve a shot at a reunion as much as anyone. But unless you're holding the album cover you'd have no way of knowing who these singers are, so completely have the Kids been filtered through the Usher Machine. Most of "The Block" is a reasonable enough approximation of faceless club pop, complete with standard-issue guest stars (the Pussycat Dolls, Timbaland) and out-of-left-field rap bridges. When the Kids hit the road this fall, songs from "The Block" will do little more than provide nostalgia-craving fans a chance to check their BlackBerrys. Jeff Vrabel
