I was sort of hesitant to share this at first, for fear that people will hate on Seth Hirsch and accuse him of exploiting Mac's name to get some attention on his single. But the song is dope, and that's what Mac Miller was about. The single is called "Say Goodbye" by Seth Hirsch featuring Mac Miller.
Seth Hirsch says of the song and Mac's part in it...
"The song’s about toxic relationships, and dealing with someone who's sh*tty towards [you], sucks up all your energy, and keeps taking advantage of your time and emotions," the Cincinnati native told Complex of the song's inspiration. "After Mac passed away, I realized this song was about a lot more than that. It's really about struggling to say goodbye to our personal demons and the chains they put on us. ... This song is such a window into Mac Miller's soul and what he was going through."
R.I.P. Mac. We love you, we miss you.
