One who absconds their heart and soul just to get cold hard cash, only to end up lower and even more poor than before when they blow it all on useless stuff and hookers.

A term people over-use for when their favorite band/artist/singer undergoes a new sound or style of playing.
Hey, did you hear Bullet For My Valentine's new album? Their a sell-out band now. I don't like the way they made their songs.

Particularly in music when an artist changes his/hers sound so it could appeall more to the masses. The most recent sell out is Bon Jovi. Or when someone snitches on you so they wont have to get in trouble. So they sold you out.
Bon Jovi is a sell out.

A genre of music which is sort of like pop or R&B, but is entirely created by rich producers who engineer it just to sound appealing to retards. These producers then find an untalented and somewhat attractive vessel through which to spread their awful music and acquire undeserved wealth.
Some famous Sell-Out artists include, Ke$ha, Jason Derulo, Justin Bieber and many young artists created by Disney who are famous amongst the mentally challenged for their acutely similar songs which is very comfortable for their fans, who are disconcerted by change, much like infants. These retards subsequently keep the Sell-Out genre alive and real music dead.
