Hehe, DB editing isn’t for the faint of heart 😉
Copy your songs.db to the PC and go down with sqlite command line tool, or the FF extension.
The access to the DB is read-only probably because firefly was still running.
Export them and then inject them into the real songs.db (or create a new one if that fails)
Pretty much same game as last time for you 😉
