i also don't care about features and i think they have way too many features in rap music. especially in the mainstream when it's done for nothing else but fame/economical profit.
but having said that, i think the Twista feature is definately something i look forward to because having tech and twista on the same track makes them both wanna give their best/craziest shit on a track... trying to out do each other in a friendly way... and something that makes you wanna try top yourself, like i'm sure this feature does, is always a plus.
same thing with the brotha lynch feature.. they feed of each others "energy" and probably come up with sicker shit than they would have solo
so i was sorta looking forward to the eminem ft too...
so you can see how those are positive features i guess...
if tech had some industry cat, some normal dude like i dunno, someone who's got flow but no personality or a definate style, it wouldnt do anything for the betterment of the song. it would just be a song with a quest rapping a verse on it, like most of the features you see
