I see this about someone who after many casual relationships and probably a few serious but failed relationships finally finding the person with whom he wants to spend the rest of his life.

@Derf important add about the serious but failed relationships as I do believe the "gettin' in tune to the straight and narrow" means, in addition to the obvious that he's choosing someone for the right/better reasons other than convenience or social constructs. Harmonizing with a divined relationship.
