Young New England was great, despite seemingly everything that was written about it, and a seven-inch of acoustic tracks we've already heard a thousand times probably isn't what they really need to make any "bounce back."
You are the 1% of Transit fans that believe YNE was great. Both online, and in terms of people that react at shows. I'm a mega Transit fan - they're my favorite band of the last five years. But, it's clear they took a massive hit. Something Left Behind was a fan loved release that was filled with 80% old songs redone acoustically. There is a high chance that if people love the acoustic renditions of these sounds, regardless of disliking YNE, that they will regain interest from fans online and physically at shows.
