A bullshit thing that tells you what's in and what's out. I dont see how people actually listen and go along to the mainstream. If they to go along with said mainstream, they're probably brainwashed. Most Mainstreamed stuff is shown on MTV

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."
