If you have a Pro subscription, you can add your music to your beautiful mashes so they are more memorable than ever.
To do so, follow the usual steps to add music, but tap on "My Music" instead of a 1SE track—the Music app will pop-up.
Please be aware that to protect copyrighted material, publishers use Digital Rights Management (DRM) technology that prevents songs from being illegally used or distributed. You can read more about it here.
DRM means that you cannot use music you don't own, for example, music from your Library that you have downloaded using an Apple Music subscription. You'll need to purchase and download the song from the iTunes store to use it in your mashes—you can't use music stored on iCloud.
* Custom music is only available in the iOS app for now.
