If you, or one of your artists/managers, identifies an Original Audio on Reels that is, in fact, one of your sound recordings, then you can manually request Attribution for this Original Audio (meaning that Instagram will re-title the original audio to an official sound recording, and this Reel and all others created with the same audio will be aggregated on the Audio Page associated with the official song).
Note that Instagram will only be able to execute this Attribution switch for you in the event that the Original Audio is an exact match of the official recording in our Audio Library. Any mashups, remixes, or songs with voiceover cannot be replaced right now.
