Im not really sure how to do that in GameMaker...
Other than that it's more than enough time as long as the project scope ain't too large. And rhythm games are large scope.
Thank you for playing my game ;)
Package as Zip
if this option doesn't appear go to
Preferences --> Windows --> Default packaging type
set to "Show Dialog"
