If you need the Art Track for one of your sound recordings to be taken down from YouTube, issue a takedown request using the same method you used to deliver the original sound recordings:
Upload a new version of the Art Track upload spreadsheet with the ownership rights removed for the tracks you want to take down. Any track without a value for track_territory_start_dates is taken down.
Submit a new DDEX file that has the
<EndDate>tag set at least two days in the past (to account for time zone differences). Learn more about takedowns.
