Just watched the live stream video on Mike's Instagram. He mentioned a new song is coming out "soon," but no date mentioned. He also has a post saying he just finished a music video. He plays about a 30 second clip of the new song towards the end of the live stream. The clip appears to be the chorus and the lyrics go "even when it's not about you, all of a sudden it's about you" before transitioning into a rap. Not sure if this is worthy of a new thread, but figured I'd pass this along.
Just checked the Post Traumatic album on iTunes and it shows a new song called "About You" featuring Blackbear. I believe he worked on "Sorry for Now" from the One More Light album. The song is not available yet, but I'd imagine it will come out by Friday.
