I started moving away from a lot of mainstream hip-hop back in the late 90's, and it actually pushed me into trip-hop, acts like DJ Shadow, Massive Attack, Sneaker Pimps etc. But then that led me into acts from the Quannum Label for example. Much like others have said, I just needed a more organic sound to what I was looking for.
I'll never give up on it as a whole, majority of my music is still rap and still comes up on iTunes or on the iPod whenever I'm driving, I'm just not checking for most anything new because a lot of what comes out is the same.
