Young Thug's either first or second mixtape of 2015, depending on who you ask, is here

Last night the rapper debuted Slime Season, an 18-song release that follows April's Barter 6, which was released commercially and has therefore been considered his debut album (think Drake's If You're Reading This It's Too Late).

And surprise, surprise: Lil Wayne makes an appearance. Stream it here:

Yep, the same Lil Wayne who has feuded with Thugga in the past, the same Lil Wayne whose Carter V is the reason Young Thug's Barter 6 has a B instead of a C. The very same Wayne whose tour bus was shot at and potentially linked to—you guessed it—Young Thug and former Weezy mentor/now sworn enemy Birdman. "Take Kare" is the first track on the tape and was originally released nearly a year ago.

As for the rest of Slime Season, which itself was originally planned for a July 4 release (naturally, the day Wayne's Free Weezy Album dropped), Migos' Offset and Quavo appear on "Quarterback," with London on da Track, Metro Boomin and many more credited as producers.

Slime Season precedes the release of Hy!£UN35, Thug's next full-length, though a release date has not been set.
