No, the out of sync drums are completely intentional. Listen to Metallica's Big Four shows, it's a combination type of parody. At the Big Four shows, it's obvious that his drumming is super out of time. At 2:25 there is an artificial tempo change completely for fun and there are various speedups at some points, as well as the snare hits being totally off. Everything bad has been accounted for, and was completely intentional. It's meant to be exaggerated for comedic effect. I'm glad you guys are being so thorough with the feedback, but after listening to the backing vocals I think it's funny that anything in this mix could be judged seriously. Keep doing your thing.
