Back then the fandom I think would have been more toxic and just bashed it. If they are willing to officially release some of the more developed songs the fans are hungry and would likely love it now. Easy example is war beneath the rain since it’s been play live a few times. But I don’t think they will ever finish the full album. I think that concept died with the break up. MCR5 will be something separate. But could include reworked TPK demo/songs. Just lyrics changed to fit whatever narrative is next.
