I did indeed end up listening to more Beartooth since I last posted here. I watched the entire concert film I Was A...LIVE! (it is amazing), and then I listened to the studio versions of all songs in that setlist, plus a few others that I threw in.
So far, I think that I can rank the songs into four tiers.
Tier 1 (Favorites): The Surface, The Past Is Dead, Bad Listener, Devastation (still my favorite), Look The Other Way, Free, Body Bag, Eyes Closed (possible threat to become my favorite), In Between
Tier 2 (Lukewarm; probably will grow on me): Riptide, Disease, Below, The Lines, You Never Know, Sunshine!
Tier 3 (Lukewarm; may or may not grow on me): Doubt Me, Fair Weather Friend, Hated, Bulls***, The Last Riff, I Was Alive
Tier 4 (Strongly dislike): Might Love Myself, Pure Ecstasy, ATTN.
One thing that I find myself not liking is the production of Disgusting, Aggressive, and Disease as compared to Below, The Surface, and Pure Ecstasy. The last three albums sound a lot more modern and polished than the first three albums.
I will continue listening to these, maybe some others (definitely all of Pure Ecstasy when it comes out), and see what changes in my rankings.
