I can't hear lyrics in songs. It's not that I'm a melody guy either. A friend pointed out that the song I wrote about below was "sad." I had no idea. I can hear words, and generally repeat them in tune. This leads people to incorrectly think that I know the lyrics and I get them. Not true.
This leads to problems when I tell people, usually girls , how much I like a certain song. Then they listen and start weeping when the song's lyrics have to do with a guy who's not really in love, but faking it. Or a girl who's boyfriend cheats on her and leaves her.
It might come from singing a cappella and therefore just singing "doom doom ba da doom" in most songs. I can pick out the percussion part, and the bass line. But those mournful lyrics pouring out of the singer's mouth? Natch. Like the teacher in Charlie Brown.
