To each his own. What I meant by E-40 blowing up was that of course he's been around for years and is a well known cat in the rap game, but I mean blowin up in terms of album sales. There's a handful of cats on the BART forum that don't like the album but are picking it up anyway because they recognize the importance of it to the Bay. I picked up 2 myself and gave one of them to my friend.
You can look at hyphy as a rip off of crunk if you want, but the bay has been ripped off way more times than anybody else has. And if Lil Jon is backing it that shows that it's not much of a rip off. IMO it is way better than crunk. It's more uptempo, better lyrics, and it's not just music either. They got their own way of dancing, dressing, talking, driving, etc. Crunk didn't have all that.
