Ensure the link is public or shareable (not private or restricted).
For Google Drive or Dropbox links, check sharing settings and make sure “anyone with the link can view” is enabled.
Avoid temporary links that expire before review.
Test your link in an incognito/private browser window to verify accessibility.
Tips:
If using a streaming platform, ensure your track is playable without login.
Label your track clearly with artist name and track title for easier review.
