In the eyes the very newest members of any band's fanbase: any band after any album they release; that same band once they work hard and earn the respect of a large-scale audience by giving the world music various types of people can enjoy. "HOW DARE THEY BE SUCCESSFUL? THE SELFISHNESS OF IT ALL! I WANT THEM TO BE BANKRUPT AND MISERABLE AND COMPLETELY UNKNOWN, THAT WAY I CAN RECOMMEND THEM TO PEOPLE WHO TELL ME 'Nah, I'll pass.' !"

2. A nonsensical term slung about by high school students to describe bands they have no true interest in (only their t-shirts) after the band released an album said fans were not even born early enough to experience. see also: False aging/wisdom/experience in a teenaged body

3. A band that truly is only in the music industry for the money see also: Metallica/Slayer/Tool/Avenged Sevenfold

4. A fan who is truly only in a fanbase for the sheer trendiness.
STEVE: "My kid brother's really into Metallica."
GREG: "Really? That sounds rich! Hey Alex, what did you think of Death Magnetic?"
ALEX: "Oh my fucking God, don't even get me started on that bunch of sell out nerds with a clear opera fetish! Trust me man, I was at their very first show back in nineteen-eighty-whatever and take my word for it: they haven't made a good album since Ride the Lightning, which was WAY better on vinyl, by the way!"
GREG: "Um, Alex, you were born in 1996. Records are obsolete and no one even makes record players anymore."
ALEX: "What's you point, faggot?"

Top Definition
One who betrays a cause for personal advancement.

The popular definition of sell out allows it to be used as an insult towards anyone in show business. On the contrary, there are many bands which are considered sellouts which are not.

For instance, Green Day. They are considered sell-outs because they are a punk band who was popular on MTV. Green Day never stated that they would never be on MTV, thus they are not sell-outs in that sense. They never changed their musical style for monetary reasons, thus they are are not sell-outs in the more literal sense of the word. If Fugazi were to sign up with Sony records, they would be selling out because they preach against major labels.
"Man, you are totally a sellout!"

Anyone who sacrifices artistic integrity in an effort to become more successful or popular (generally in music); someone who forgets their roots.
It's the American dream to be a sellout.

when a band/singer/rapper changes their music/style in order to sell records.
gwen stefani is a 'sell out'.
A vague but derogatory term blindly used by music "fans" to describe bands who make (or have managers who make) a new lucrative and/or artistically experimental decision (for example: accepting a product endorsement, a change in the band's expected composition style, switching to a larger record label, dressing with more class, speaking out against mass mp3 piracy, etc.) The word is sometimes also applied to bands who simply get more commercial success through no additional effort.

The anger comes from the false belief that fans "own" their favorite entertainers, that these entertainers are thus not real humans with free will, and the feeling of grief when some CD that the listener previously enjoyed alone is now enjoyed by millions of more people.

(Note that "sellout" ONLY applies to those who make a living in the fine arts. For example, a software engineer who accepts a job promotion and higher salary is never branded as a "sellout". Nor is a professional athlete who appears on a box of Wheaties.)
Actual quotes from an old friend:

(1993) "Damnit, Smashing Pumpkins is such an underrated band. They never get played on the radio!"
(1994) "Damnit, Smashing Pumpkins are always on Mtv and the radio now! They're such sellouts."

A word that would be useful if stupid poseurs didn't use it all the time.
Proper usage:
That band alienated their fan base and changed their style according to what the record company wants, that means they're sellouts.

Improper usage:
