I don't mean the new Kings of Leon record or new NME/Pitchfork/DiS buzz band or whatever, but more underground, under-exposed stuff.
This is part personal curiosity and part research.

Same question to musicians/people in bands...what routes do you take to get your stuff heard by people who will actually like it? There's three zillion myspace pages out there...there must be some better way than just hoping someone will stumble across it.

Oh lord this sounds like some kind of jag for some product. It really is not.
