I think all music should grow and evolve. BUT at one point hip-hop was about being socially conscious, about treating people equally, and getting real about problems in the ghetto and DOING something about it (IE: NWA). It was about getting involved. It was about remembering the past but push forward the future. It was about being REAL about who you are and your life. Now its a big autotune circle jerk with no emotion. I know some of you don't agree, but look at people like Jay-Z, Kanye, RJD2, The Roots, Eminem they are moving hip-hop forward (and keeping it in the charts) and still retaining the passion, the timeless message of success after struggle. There lyrics have MEANING! Look at Eminem's new album, it is intensely personal, as is Kanye's. This is what music is all about.
Seriously, FUCK Black Eyed Peas, T-Payne and anyone else that can't write lyrics for shit and rely on gimmicks only YOUR ARE NOT AN ARTIST as you don't create ART!
