Chris Brown is celebrating the release of his new album Indigo and while he got a host of celebs to collab with him on tracks - Justin Bieber, Nicki Minaj, Drake, Lil Wayne, H.E.R. -- NONE of those people turned up last night at The Nice Guy to party with the man of the hour.

Why? Well you might say it could have something to do with Brown's past, which absolutely NO ONE has forgotten about. Why'd they agree to collaborate with him in the first place? One might wonder ... but music journalists and former fans alike are reminding the world about Chris' negative past.

Newsweek's headline is: "Chris Brown's New Album Indigo Slammed By Those Who Remember His Abusive Past." They point out Twitter haters who've posted comments like: "Again folks are raving about Chris Brown. I literally feel sick. I will never feel safe in a society so willing to excuse the abuse of Black women," and "A reminder to everybody who's listening to his new album that Chris Brown is an absolute garbage waste of air of a human being."

Others say we should separate the artist from his art but ... yeah, right. Enrich the b*tch. Not cool. Sorry, Chris -- ya did it to yoself!
