I don't.
Yeah, it's good. Yeah, it's lengthy, two full minutes longer than LP's previous longest studio track (not counting She Couldn't). The best ever? No. It's got that emotional feeling, it's got the solo, it's got the badass a cappella climax, and most importantly, it's got Phoenix singing live. All good things. But it's not their best studio track ever. The song feels full and powerful on the first few listens, but once you've gone through it several times, it loses that...punch. It falls flat, like soda that you left open.
I'm not going to say what I myself think is LP's best studio track. But it's not TLTGYA.
