Hombre si solo es editar el db3, no lo hagas con un hexadecimal, es una base de datos, tratala como tal xD Voy a revisar el contenido
EDIT:
Mira el contenido del MusicDB es este

Y mas entradas con el resto de canciones, pero ahora no tengo el MusicDb2_4D530888_7.db3 y no puedo comparar, mañana lo cogere y repasare
No creo que dé demasiados problemas...
