Lupe Fiasco has never shied away from controversy over his career, but his latest may be the nail in the coffin. He uploaded a new song or freestyle to his SoundCloud titled "N.E.R.D." where he raps over the beat to J. Cole's "Everybody Dies." In the song he calls out "dirty Jewish execs," which obviously has caused some uproar. SoundCloud apparently took the song down for a short period of time and Fiasco decided that was enough, claiming he is going to retire from the music industry. Sticking to Twitter, he also had a pretty protracted beef or discussion with Anti-Defamation League (ADL) CEO Jonathan Greenblatt on the subject.

On the track, Lupe raps about half way through "Artists getting robbed for their publishing / By dirty Jewish execs who think that it's alms from the covenant."

After SoundCloud apparently took down the track, he made the proclamation yesterday that he was done with music. "I'm officially not releasing anymore music. Albums canceled," he wrote on Twitter.

The news started to spread and the ADL released a statement calling the lyrics "offensive." The statement continues, "These lyrics reinforce the anti-Semitic myth of Jewish control of the music industry, a stereotype that has been exploited in recent years by well-known hatemongers. It is irresponsible for a recording artist to perpetuate the hateful anti-Semitic stereotype of the 'greedy Jew.'"

Lupe and ADL CEO Jonathan Greenblatt then went on to have a discussion of sorts on Twitter where Fiasco defended his record as a multicultural person and artist, despite the comments.
