That's me as well, I'm not in this for the lyrics or else I'd be into poetry, which I'm not. I don't care too much what the lyrics say as long as the music is there. But, I happen to be a good singer as well as a good guitarist so I can accent one or the other or both depending on the song. And I am absolutely about harmony, which is why our act has three people.

As to what I like to hear, if someone is overwhelmingly good at one and not the other, that's OK depending on level of competence. It's when someone is good at neither (read "bar owner's niece") that I lose all interest.
