Mainstream music 

Commercialized music that is extremely popular among people. Depending on the generation, mainstream music may be great or it may be garbage. As of the 2000's, mainstream has been garbage. Even more recently, Pop and generic rock music has overtaken Rap music, and the mainstream is at it's apex of garbage.

Mainstream music is contantly shat out by Hollywood, and what is considered piping hot now will be forgotten in a few years. For example, all of the boy-bands popular in the late 1990's to early 2000's are nowhere to be seen.

You can find many shat-out artists such as Lady Gaga plastered all over the Myspace home page.

Mainstream music is mainstream when Hollywood says it is.

The Mainstream 

A machination of the corporate world. Designed to target a creative outlet and turn it into a business model, target market, key demographic, etcetera.

How the mainstream operates:

1. The mainstream is established...
2. An alternative is established to the mainstream...
3. The mainstream targets the alternative...
4. The alternative becomes the mainstream...

And therefore the alternative loses its identity, having become absorbed by the very system it was established to rally against. Mainstream for the masses...

Anti - Mainstream 

Someone who is anti - mainstream has a strong dislike of trendy things and people. Many subcultures have preached about being anti - mainstream, most notably punk and heavy metal. Death metal, Black metal, and a few lesser known subgenres of punk rock remain the longest standing anti - mainstream subcultures while others have either become popular (I.e punk) or merged into other more popular subcultures(I.e classic metal and thrash metal). While music subcultures have the biggest anti - mainstream message other subcultures based around religion (I.e LaVeyan Satanism), politics(i.e non partisans), and even literature have emerged. Most trendy things start out anti - mainstream and become popular usually after a slight change in image (I.e in the 1920's united states when white people began playing jazz it became acceptable).

Punk was the first major anti - mainstream subculture, shortly followed by heavy metal and hip - hop.

Mainstream Whore 

A mainstream whore is one whom follows almost every single trendy thing they can, and changes as new things come out, or older things come back.

Mary: I mean I used to like the Jonas Brothers, but then I moved onto Justin Bieber. I am absolutely in love with One Direction now though, even though I only like one of their songs.

Susy: You are such a mainstream whore.
