The brainwash big businesses put out. They feed young adults with worthless movies and music. The trend. All very fake, they put out whatever is in style. Many are too filtered out by the mainstream's brainwash to wake up.
Very few mainstream artists are worth listening to.
"Reality" Tv shows would be an example. They saw how people watched Survivor, and they fed off it.

Somebody that only likes music that is mainstream and will probably just get worn-out soon. A person that usually just follows trends. Mainstreamers don't always have a lot creativity to listen to underground material.
Mainstreamers: Wow this extremely popular and over-advertised new music album rocks!

Mainstream is the larger public, the masses, the big crowd. Things that are or become 'mainstream' are the things that currently sell the most and gain the most popularity.

CRAPPY MUSIC that goes by the standards and implied guidelines set by other songs that are currently popular.

The only inkling of individuality is either a) the lead singer's voice, or b)the fucking tone of the guitar.
Both of those are still a rarity.

Sometimes, you can define a mainsrteam band by the ranking they are at on the top 40 list, or the iTunes most popular. But not always, because sometimes good indie music is mistakenly put there.
jock: "Dude, I just got this new CD. It's 'American Idiot' man!! I feel so bad-ass! Aren't they awesome, singing about America and shit?!"

smart indie kid: "Fuck man, don't spend money on that mainstream garbage.
Go buy some Pinback."

A term used to describe when a "underground" genre of musical expression has been fully embraced by the public media through aggressive advertising (aka MTV). Following this phase, the style begins to rapidly plummet in popularity while the ravenous leeches and posers choose to find a new fad to gnaw upon.

During the "Golden Years" of a mainstream topic, the genre recieves praise in record numbers, often represented by record numbers of identity-free morons with nothing to make themselves "stand out". It gains brief immortality during this phase, with not enough love, and not enough hate to dislodge it.

Only when the "haters" prevail in larger numbers in proportion to fans will the death sentence of a genre be finalized.
Rap music still hasn't died because for a decade, it has worked secretly to poison the urban population with wife-beating lyrics and brain-damaging rhythmes, making a permanantly imprint on the inner-city folk.

Very devilish plan indeed...
