As you probably know, Pusha T c0-wrote McDonald's "I'm Loving It" jingle, which the fast-food giant has been featuring since 2003.

But Push doesn't think he was properly paid for his work.

He and his bro No Malice got 500K, whereas Justin Timberlake end up with $6 million for singing the jingle.

"I took a super L," Pusha explained a few years back. "Just upfront, no publishing. Shoutout to Steve Stoute, he gave me the check and I was like ‘Ahhh great,’"

"I want artists to know that part. Keep your publishing. That check will be nice, but ‘I’m Lovin’ It' been running for how long now? I did this in ‘03. Who knows what it would have been," Push continued.

Perhaps that's why Push is new teaming with Arby's to promote their new Spicy Fish sandwich diss McDonald's famous Filet-O-Fish sandwich.

"Say less, this argument is baseless," he raps. "Drowned in Tarter, that Filet-O-Fish is tasteless."
