i've heard some crazy shit from taj-he-spitz lately. if he learned how to take his best music further and start building a brand around it, he'd have a shot at making a classic album. his image and way about him is kinda stuck in 2007 too — which will fuck your shit up bad when you try to transition out of the region, because the bay was a joke in 2007.
i don't know about commercial success because honestly there's a lot more that plays into it than music quality, but for most artists that aren't a weird white girl or lil b that's where you gotta start.
HD's another one that makes about 1 track out of 20 that's amazing. but he kinda has a tunnel vision in the hood category that i don't think he'll be able to shake.
funny thing is all these problems can be solved if you surround yourself with the right handlers — but whatever it's not my job. from a fan perspective i don't give a fuck if the rappers i listen to blow up or not, as long as i get to blap it in the sentra. lol.
