Q: With GarageBand music itself inside material and sound materials Made new music

Music you make with GarageBand's instruments, loops or live recordings of yourself playing or singing can be used as background music for a game provided you haven't copied somebody else's copyrighted lyrics or tune. See Using royalty-free loops in GarageBand with commercial work - Apple Support.
