New Era of Hip-Hop?

I've been listening to the new Drake and the Roots new albums today. Both are really good. I've heard lots of discussion about how Kanye's 808 & Heartbreak, Kid Cudi's Man on the Moon and Drake's album all represent a new style of hip-hop. I'm not an expert but I've enjoyed these albums more than almost anything other hip-hop records in the last three years. Am I simply part of the indie rock-loving, middle-class, music geek stereotype that cares about these random new eras in popular music? Probably but I'm still enjoying these albums
