I always think about lyrics, the song and the meaning behind it all. It's a way to relate to the song. Usually I'm quite picky, so when I like something, I do tend to dissect it and see what's going on in there. What does it all mean? And why do I like it so much? And should I like it so much?
When the lyrics are simplistic, I tend to overthink and come up with a way to make sense out of something that isn't necessarily sensible, or deep, to begin with. It's usually harmless: we rock a lot, we roll a lot, and are sometimes a little concerned about politics and the ways of the world. Sometimes it is a little deep, and there's a story to be discovered there - excellent! Someone has insight into the world we live in? Great! Escapism? Great! Politics? Why not?! Fantasy? Goofy or not, it's still great!
But when the lyrics are narrow-minded, racist, anti-semitic, stupid, and/or against common ethics, it immediately strikes the wrong chord with me, and I definitely do tend to resent it.
