When is mainstream exactly mainstream? What is mainstream? AHHHHH

Answer that ^ for me.

Mainstream? Is it categorized by how the music sounds like or how many people likes 'em or WHO likes 'em or what? Radio music?

Just wondered about this topic when I was on my way to Amath class just now.

I've had small talk topics on this before, like which band will lose their 'status virginity'? (of course it's just a figure of speech) It's more of a euphemism for probably - going mainstream? no?

Ok I confess, I used to label mainstream music in SEC 1 (13 only ok) ya ya I was Alif the naive in oh-five. But not now la. But that doesn't mean I shake my butt to the tune of any Pussy Cat Dolls song.

So.. there is a difference between labels and preference.
Because Fall Out Boy sounds like FM Static.
I prefer both :/ Aye, don't go saying "AHAHAHAH dumb [insult] listen to FOB!"
Their new album not bad ok, got screaming one. Like "Saturday".

Ok, so there's also intolerance, to add on to labeling and preference.
Intolerant to PCD
Intolerant to M5
Intolerant to Sanjaya
Intolerant to Hip-hop/R&B etc.

Aye?

So when is a band mainstream? When it's being publicized? The first chord on their song the radio is played they're mainstream? Album advertised on TV?

ANSWER MY BURNING QUESTIONS.

ok la, I'm just bored. Got Amath homework to be handed up tomorrow. & I can't find my exercise books :(
