Never forget there's always the DLID debut album or Matty's solo stuff to speculate about on top of a new 1975 album. So many possibilities outside of him just being Matty on social media.
If this is the actual tracklist we're in for a classic edit: "We Were Promised Setbacks" is the most radiohead song title
Matty recently shared this song to his Insta story "Don't be overlooking the bass player, guys. That dude was out for blood"
My current theory is that he’s been so active recently because he has a project to announce soon. Maybe he actually has a solo album. George already started releasing his own stuff too, so it’s time.
It seems like they've been working on the new 1975 album a lot already so I think that'll be his next thing.
He has said he doesn’t feel the need to do a solo album because he sees The 1975 as his outlet. I would guess it’s leading up to a new album layer next year.
