I detest love lyrics. I think one of the causes of bad mental health in the United States is that people have been raised on 'love lyrics'.
You're a young kid and you hear all those 'love lyrics', right? Your parents aren't telling you the truth about love, and you can't really learn about it in school. You're getting the bulk of your 'behaviour norms' mapped out for you in the lyrics to some dumb fucking love song. It's a subconscious training that creates desire for an imaginary situation which will never exist for you. People who buy into that mythology go through life feeling that they got cheated out of something.
What I think is very cynical about some rock and roll songs -- especially today -- is the way they say: "Let's make love." What the fuck kind of wussy says shit like that in the real world? You ought to be able to say "Let's go fuck", or at least "Let's go fill-in-the-blank" -- but you gotta say "Let's make love" in order to get on the radio. This creates a semantic corruption, by changing the context in which the word 'love' is used in the song.
When they get into drooling about love as a 'romantic concept' -- especially in the lyrics of sensitive singer/songwriter types -- that's another shove in the direction of bad mental health.
Fortunately, lyrics over the last five or six years have gotten to be less and less important, with 'art rock groups' and new wavers specializing in 'nonjudgemental' or 'purposely inconsequential' lyrics. People have stopped listening to the lyrics -- they are now only 'pitched mouth noises'.
