We can follow the same template and do the five-act split. Sonically, I'm still going to be where I'm at. Honestly, I was ready to live up to the obligation and do 'Man on the Moon III. I haven't been dicking around. I was planning on doing it after Speedin' Bullet. But the Speedin' Bullet response tore me up. It made me realize what's most important. I'm getting back on the bike again and doing what I do best: me." On April 22, 2016, Kid Cudi announced he would be releasing a new studio album, slated for a summer unveiling. On May 11, 2016, amidst rumors that he was set to release Man on the Moon III, Cudi revealed the title of his sixth solo album would be Passion, Pain & Demon Slayin', through online mobile video-sharing and social networking service Instagram.
