Two different eras in my life:
13, 14, 15 = Audioslave, Shinedown, Metallica, Nirvana, Soundgarden, STP, Linkin Park. Anything to rebel against mom and dad. Still listen to it, but not as much.
College Years = I got really into Cross Canadian Ragweed and have fallen down the rabbit hole of Country Music (Non-Radio). Jason Boland and the Stragglers, Reckless Kelly, Mickey and the Motorcars. That has moved way more towards the Americana/Alt-Country Spectrum. Right now my top two are Jason Isbell and Cody Jinks.
