Best Thing in Town song meaning

The lyrics are exaggeratedly abstract - the narrator is trying to show that this person he considers the best thing in town makes him almost lose his mind. He's describing his confusing state of mind ("all I see are sounds", "...I can't find a missing piece of a thought that's in my mind"), yet admits that he's willing to do crazy things and eagerly accept all the weirdness of this relationship, because he's convinced that this person is worth it, since they are "the best thing around".
