THERE'S TUNE, TOO, Y'KNOW. In most music, at least.
Mostly what I listen to is melody. Instrumental, vocal...
Though, by listening to the vocal melody, I catch the lyrics. They don't really matter much to me, but I do listen to them, memorize them, and spit them out. If the lyrics are particularly good or particularly bad, I will take note, but mediocre lyrics don't have any effect on a song for me.
