underground 

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

Underground 

The Space of matter beneath the ground. Mostly thought to be considered only the earth's crust layer.

When someone dies, they are sometimes buried 6 feet underground.

Underground 

Simply put, it’s an elite form of music or lifestyle not typical of the mainstream

Wow, Kyle wishes he was underground but just isn’t

underground 

A twenty-first century marketing buzz word used to convince teens that the over-hyped, over-produced, corporate-friendly crap they listen to on the radio station everday is actually "unique, hip, different" or that they somehow aren't part of a target market in which they all obediently buy the same crap.

Yeah, that hot new underground rapper made his debut on TRL today.

Underground 

Something I greatly overvalue in order to escape from my low self-esteem in order to be able to tell myself I am superiour to every form of life.

Someone1: Hi, have you met my friend Amar?
Me(to self): He calls me his friend? How can that be? How can he possibly like me.. Oh wait it's in your head Amar.. it's in your head.
Me: I listen to artists that are so underground they have 600 hits back on google, that's why I own you. I own, I own. Muahahah! I own! Bow before me!! Puny mortal! Bow before me!
Someone2: Is he crazy?
Someone1: Yes.
