This song is supposed to have some irony and sarcasm. He's trying to explain to people how music doesn't need words to be good, but he has to use the words to say that. And no, lyrics aren't all that matter. Sure, certain singers can convey emotions with both their lyrics and voices, but lyrics shouldn't completely define a song. Of course, on this site that's all that'll be talked about because songs without lyrics wouldn't be posted here.
