What's on your mug?

in simple terms, the opposite of mainstream

underground rapper Canibus got some beef wit Eminem, who is mainstream.

underground is like deeper beats, lyrics and soul to a song - commercial is like what get's played on the radio and is marketed to the masses - Britney's mainstream, Eminem is mainstream - even though anyone can make underground music they don't coz it doesn't sell like commercial stuff - underground IS deeper, more hardcore, more controversial, or whatever...

sup the chenist - dust c.d is underground.. you'll know the difference if you know your music... NB: It isn't underground because it hasn't hit mainstream yet - it's whole design is different to mass appeal.

Does NOT have to be unknown, it can also be a rapper that was underground yet kept the style and became extremely popular and well-selling commercial material

Pharoahe Monch and Wu-tang clan have music that is not bombarded with commercial material yet sell heaps
