A lot of great albums in this thread. One that I always bring up with my mates that is mint from start to finish but criminally underrated, is Bleed American by Jimmy Eat World. That album kicks ass.
Edit: in keeping with my post-2000 albums (because the classics have already been mentioned), I haven’t heard anything punk/hardcore top Rise Against - Appeal to Reason.
Too hard to do a top 10, and too hard to do any order. Respect for those that can manage it.
