if you want some intros to crunk and hyphy, i would recommend lil jon's throw your hood up and kings of crunk albums. for hyphy, check out e-40's my ghetto report card or the federations album. im not saying theyre the be and end all of the genre, but if you try and grab a load of mixtapes, youre bound to have to wade through a lot of dross along the way. those albums are probably good starting points.
