When uploading your release, simply choose “Instagram & Meta” as a store, and your music will appear in the audio libraries on both platforms.
This allows users on Instagram and Meta to find your tracks and include them in their Stories and Reels.
Keep in mind, though, that if you want to earn revenue from user-generated content (UGC)—videos where people use your song without selecting it from the audio library—you’ll need to upgrade to eMastered’s Social Media Monetization release extra.
