The personification of "the piper" in verse 3 is the standout move of the whole song. Turning an idiom into an actual character who speaks — and giving him a line as good as "I don't come here to punish or scold; I just come to make whole what was broken and old" — completely reframes the song. It stops being about dread and becomes about redemption. That's a real structural swing, and it pays off, nice song writing Billy!
"Karma's a ledger and karma don't lie" is a great line — concrete financial imagery married to a moral concept, which fits the song's whole "debt" metaphor perfectly.
"Reaping the wind that I blew long ago" is a nice twist on the "sow the wind, reap the whirlwind" idiom — familiar phrase, personalized just enough to feel like yours. You've got scholastic skills here and extremely good poetic texture! 
The bridge is doing real emotional work — "maybe facing the music is mercy in disguise" sets up the turn in verse 3 well, so the piper's grace at the end doesn't feel like it comes out of nowhere.
The outro's "but maybe... just maybe... paying sets you free" lands as a genuinely earned final turn, converting the whole song's dread into resolution.

This is confident, genre-aware songwriting with a real narrative arc — dread reckoning to grace. Strong work bravo Billy, bravo!
