J. Holiday/Trey Songz

Saying you want to combine old-school soul and modern R&B has become boilerplate in the bio of just about every young urban crooner these days. That hasn't deterred D.C. native Nahum Grymes and Virginian Tremaine Neverson — better-known as J. Holiday and Trey Songz — from making their own fresh-faced attempts at the formula. The latter singer has the stronger rep (he was touted by the late Ahmet Ertegün as a key signing to his storied Atlantic label), but it's the lazy-voiced Holiday who's scored the biggest hit thus far, last year's Top Five smash, "Bed."
