We recommend including in your description, "An MP3 accompaniment track is available for this title!" or "Sheet music for this MP3 track is also available!" Encourage customers to search for "[TITLE] [YOUR PUBLISHER NAME]," which should take them directly to the correct results.
Currently, when you copy and paste the direct URL link for an MP3 asset into the description area of your Sheet Music score (or vice versa), it will cause a processing error that will leave your asset unpublished. We do not recommend including product links in your description.
You may also create a TinyURL, which will not cause the processing error mentioned above and has the added benefit of allowing you to create a custom link to related titles and share more easily on social media.
