Something that's popular. Sure, it's trendy, sure, it's probably on MTV and popular among people-but, honestly-is it really that much of an issue if I have Lady Gaga on my Ipod? She's in there with Amanda Palmer and Porcelain and the Trams as well-am I indie enough for you?

The lot of you are being really rude. Some mainstream is good, it's not the end of the world, so stop complaining that somebody else likes Rihanna and you like The Decemberists.

Grow up.
Person A: Hey, have you heard the new release from Lady Gaga? It's pretty good. I think I"ll give her a chance!

Person B: Umm..that stuff is forced down our throats by mtv and stuff. You shouldn't listen to that. Here, I got a new album based off of a Pitchfork review, you should try it.

Person A: *listens*
Yeah...no offense dude, but I don't like it.

Person B: *scoffs* You're just another one of the sheeple. A slave to the mainstream. You just have bad taste.

In the opinion of morons, such as almost everyone posting on this page, mainstream is the epitomy of conformity and capitalistic exploitation tactics. To follow mainstream, in the opinion of such idiots, is to be weak and conformist.
Mainstream is marketable and appealling to the masses because it's popular and more likeable. Most "non-mainstream" artists would do anything to become mainstream.
Mainstream is frowned at by morons between the ages 14-24 due to their inability to see the wood through the trees.
