The best part of being a songwriter — beyond being able to make a living at it — is what I call the "heart payment" of a song. That's when somebody comes up after a concert and says, "My mom was a single mom, and 'You And Me Against The World' was a really important song to us." Or "We got married to 'We've Only Just Begun'" or 'Evergreen.' Or "'I Won't Last A Day Without You' got me through some hard times.'" That's heart payment for a songwriter.
