I really dig these songs more than "Danger Days", I think it's clear they should have released these instead of that record.
Technically danger days was pretty sucessful. This just means you get more music in the form of DD and Conventional Weapons. They are not a band to write the same album twice so I doubt another Danger Days is in the works and it was an experiment. As polarizing as it was among fans it sold well. Not as well as previous releases but Gold in multiple countries is still pretty impressive these days. Also after receiving mostly positive reviews and rekindling the spirits of the band to keep going its hard to say releasing the album was a bad idea. I love Conventional Weapons and to a degree find a lot of songs better than Danger Days but I doubt they would be a band still if they had not released it.
