A band who changes their music to include more poppy parts, to gain popularity. Often confused with "getting famous", "getting better sound" and "writing less heavy music".
Prime example - lostprophets (re-releasing an album that was only 2 years old, to make it more 'accessible')

Bad examples: blink 182 (just got a better sound) incubus (got old and wrote more chilled music) and tool (just became popular without changing anything)

when a person (most oftenly a musical artist) comprimises their beliefs to further their success and make loads of money. However, this is not to be confused with when a band that you liked, that was perviously not popular, becomes popular.
britney spears sold out when she decided to take off all of her clothes in order to see more albums.

Metallica
When Metallica bitched about their fans trading their music online because they weren't getting paid, they became sell outs.

"Selling out is compromising your musical intentions and we don't know how to do that."-Mike Dirnt of Green Day. I couldn't have said it better myself, beings as it's hard to define a sellout.
Selling out is kind of irrelevant because if you start out in music not wanting to sell out, people are still going to like you. And when 10,000 people come to indie label shows it gets crowded. So go ahead with the major label if you need room to grow, just don't sell your soul or mangle your music to do it. A 'sellout' probably doesn't give a shit whether you like them or not.

1. A band that changes it's style for stupid teenybopper girls and getting more money, even though they already have tons of it.

2. A word used by teenaged wannabe goths/punks to sound hardcore. Those people usually come up with bullshit reasons like "WE DON'T WANT TO CONFORM TO SOCIETY" and say "THEY BECAME POPULAR AND STARTED TO SUCK".
1. Good Charlotte, Maroon 5, Blink 182.

2. "OMG OMG I WANT TO SOUND HARDCORE I CRAVE TO BE HARDCORE SO I SAY THEY ARE A SELL OUT".

What envious underachievers call artists, writers, actors, or musicians when they no longer conform to their expectations.
Band X changed instead of staying exactly the same. They're sell outs!
