BH Buzz: Drake Releases Meek Mill Diss Track Titled "Charged Up"

Catch up on all the latest music tidbits while recovering from Friday’s hangover (and the inevitable one from Saturday).

■ Drake released a song titled “Charged Up” presumably about Meek Mill, who recently claimed in a public Twitter rant the “Energy” singer doesn’t write his own raps. Mill alleged Drake hides behind ghost writer Quentin Miller, who’s since publicly denounced those claims. Miller wrote a message on Tumblr saying:

“I am not and never will be a ‘ghostwriter’ for Drake.. I’m proud to say that we’ve collaborated .. but I could never take credit for anything other than the few songs we worked on together.”

“I did some charity today for the kids,” Drake raps in “Charged Up.” “But I’m used to it ‘cause all y’all charity cases. All y’all stare in my face in hopes you could be the replacement. N—–s snitching on us without no interrogation. I stay silent ‘cause we at war and I’m very patient. 6 God is watching, I just hope you’re prepared to face him. I’m charged up, i’m charged up.”

You think Meek Mill cares? ¯\_(ツ)_/¯

Drake also premiered two other songs. One titled “Right Hand,” the other a remix of “Cha Cha.”
