look up any word, like plopping:

Something that is liked by a majority of people and doesn't pertain to any particular subculture. Mainstream is not a particular style of music, it has nothing to with rap, it has nothing to do with the media forcing various types of music down our throats. It's just stuff that a lot of people like. That's it.
And as for the people saying shit like "Mainstream should die"... What do you think would happen if everyone started listening to the more underground music that you like?

It would be mainstream. Faggot.

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."

A person (or more commonly persons) which follow the common/accepted/most seemingly popular trend. The trends are normally labeled, causing a divide of those who conform and do not conform (non-conformists) until the non-conformists become the common trend, creating a cycle.
Today's common mainstream trends are labeled as 'emo' (Many of these titles are misused). The older term for the jumping of trends is 'Fashionista or Fashionister'
