Last summer's most exhausting rap beef is officially back, with Philly's own Meek Mill again trading barbs with Ontario's finest, Drake, in a newly released track.

Over the weekend, Drake took aim at Mill with "Summer Sixteen," a new single the rapper debuted at his OVO Sound show on Saturday in response to Mill's "I'm da Plug Freestyle," which recently stirred up the long-dormant feud. In it, Drake mocks Mill, rapping that "I could have killed you the first time." The track is currently available on iTunes.

Mill, for his part, responded to Drake's latest diss almost instantly, putting up the track "War Pain" as part of his latest EP release, 4/4 Pt. 2. Oddly, however, the track features Mill's firey responses to the Drake track, which was released about a half-hour before Mill's own song dropped.

Mill explained that particular development on Instagram, saying that "The ghost writer told me," referring back to the ghostwriting accusation that started the beef in the first place last summer. That initial accusation lead to the first round of feuding last year with the release of Drake's "Charged Up" and "Back to Back," as well as Mill's "Wanna Know."

Their feud, however, isn't the only thing the two rappers have going. Drake, as he announced over the weekend, will release the highly anticipated Views From the 6 on April 16. Mill, meanwhile, is currently awaiting a sentencing hearing this week in connection with parole violations from last year.
