Everyone knows that sex sells. Crooners like Trey Songz and Tank have the tendency to strip down to a tissue-thin undershirt onstage, while belting explicit lyrics using beautiful melodies. The crowd -- mostly filled with women -- subsequently erupts once said shirt is taken off. This is the formula and the hottest artists in the genre know how to play it up.

There's something to be said about a man with toned muscles standing in a spotlight unable to keep his clothes on; it's a fantasy for millions of ladies. These sexy singers peel off layers while the public keeps a close watch, reveling in the eye candy.

Here, TheDrop.fm finds 10 guys who, at some point, couldn't keep their shirts on -- not that we're complaining. Check out some R&B Hot Bodies.
