AC/DC
Every single that AC/DC has ever recorded was about sex, guns or drinking. It's true. I can't rightfully think of one song that's not about any of those in some form or fashion. Which isn't bad, really. You will like their Back In Black playlist, though you may need to Google some of the lyrics.
Apparently a girl's "motor" is her vagina, and the girl in "You Shook Me All Night Long" kept hers clean, though she was in fact a prostitute. (Would it weird you out if I told you that when your mom was a bartender on Sixth Street in college in the '90s, she made a lot of money when that song was playing?)

Pink Floyd
You remember that music your parents or teachers would play when you were really little to make you nap or go to bed for the night? Pink Floyd's entire career was that, but with a few songs about politics and animals.
You've heard "Another Brick In The Wall" at least a dozen times, and may not even know it. The "Hey Teacher!" song on the Arrow while you were waiting for mom's oil to get changed? That's Pink Floyd. No one in the band is named Pink or Floyd, by the way.

The Eagles
Kings of Leon are sorta like the Eagles but for today. The Eagles sang a lot of songs about breezes, dating crazy chicks, and generally having mellow times and wearing jeans. It's kinda boring sometimes, but the songs with Joe Walsh were fun.
