I think it's interesting because lyrics can make or break a song for me, but Ryan is the opposite. It doesn't matter how witty or clever the lyrics are if he can't get behind the sound (though I'm sure this has to do with his ability to actually make music himself). I, on the other hand, will even listen to genres of music I don't particularly like if I like the lyrics enough. (I also write down lines of songs I like for inspiration.)
I'm just amazed anyone would go out of their way to be not lyrical.
