No. „underground“ is the antithesis to „mainstream“. Both are words and part of english language. It is not all down to individual opinion.

[wturner]

Okay - let's play. How many people need to hear a song or artist for them to be designated "mainstream"?

[edpichler]

Mainstream is when it’s broadcasted on non interactive media channels nationwide.

[wturner]

According to your definition if some kid happens to get their music played across the country soley on college radio stations then they are mainstream.

Would you rather color it underground? Do you expect that piano piece to be obscure and stylistically uncommon?

[edpichler]

Yes! Why it wouldn't be? I am here to learn, please, how do you define mainstream?

[fenomas]

Just because there's a Sorites paradox doesn't mean the word is meaningless. This line of objections isn't constructive.

[wturner]

I never said it was meaningless, I said it was subjective.
