I'd say songs are oral, just that music is an aural experience.

Music is an aural experience, not an oral one! Personally I don't care about the lyrics. I barely notice them. I feel like those who say they are of equal importance must have genres they're not keen on, so an artist could be writing the best lyrics you've ever seen, but if you don't dig the tune, you're surely not going to want to listen to it just for the words?

But I also feel that any aspect of any art is in the eye of the beholder, so how and what any one person enjoys is no more or less valid than anyone else, so knock yourselves out!
