its his decision, right? and he hasn't publicly voiced his opinion on why he removed them although we all know its due to a move in the film industry. he has proven himself (in terms of success) in the music industry and now wants to venture out into different areas, similar to ice cube who has conquered the hip hop industry and ventured out into movies and the small screen.
i don't care what people say about ice cube saying that he's "gone Hollywood", in fact i enjoy his films as well as his music, so long as he keeps bringing that heat with a classic west coast sound. now on an independent label, it should give him even more freedom to make the music he wants, its just a whole lot better, potentially. and im looking forward to hearing Young Maylay on his new album "I Am The West". I just hope he really makes the final cut, would like to hear more WC too - its been a while...
Anyway, Cube is committed to doing entertainment whether that's in music or film, book or whatever... this guy is a legend and i will always want to hear or see what he has come up with; the same for 50 cent who has brought a lot of controversy just like Ice Cube has repeatedly done since his N.W.A. days.
But yeah, DMX too.
