Meek Mill finally released a diss track in response to the jabs that fellow rapper and former friend Drake posted earlier this week, in a song titled "Back to Back" that was met with critical acclaim. Mill's track "Wanna Know" premiered on New York hip-hop radio station Hot 97 last night, according to Complex.

Mill backs up his initial claim that started the back and forth hip-hop battle with Drake, when Mill accused Drake of hiring a ghostwriter to write all his lines. In "Wanna Know," Mill names Drake's alleged ghostwriter in a reference to the hook to "Know Yourself," one of the hits off of his unannounced 2015 release "If You're Reading This It's Too Late."

"I just wanna know, if you ain't write that running through the six sh** / Tell us who the f*** was Quentin running through the six with?," Mill raps, according to a transcription from Genius. This line is followed by a clip of Quentin's original recording of the hook Drake used in "Know Yourself."

Mill takes lackluster jabs at Drake over a beat produced by Jhalil Beats and Swizz Beats and features a sample of WWE Wrestler The Undertaker's intro song, according to Rolling Stone.

It's unclear whether Drake will choose continue the feud and hit Mill back with another track, but he posted a photo to Instagram that could sum up exactly how he feels about Mill's song.

In the photo, Drake is holding his iPhone in front of him and is engaged in a hearty laugh. He didn't caption the post, but it was uploaded shortly after Mill dropped his track, so it's speculated that the post is meant for Mill.
