Bulk Match Submission Process

The Bulk Match Submission Process complements the Matching Tool in The MLC Portal, which is used by thousands of Members to search for unmatched usage of their registered works and propose individual matches. With the Bulk Match Submission Process, Members can submit an unlimited number of proposed matches between sound recordings and their registered works, making it easier than ever to address large volumes of unmatched recordings.

Guidelines

These guidelines specify the required format and content for CSV files to be submitted, containing information about the proposed links between ISRC and MLC Song Codes. Proper adherence to these specifications will ensure seamless processing of your data.

How do I submit match suggestions through the Bulk Match Submission Process?

To submit your match suggestions, follow the instructions outlined in the "Bulk Match Submission Process Guidelines" page, detailed above. If you need additional assistance or encounter any issues, please reach out to us at publisherservices@themlc.com.

How will I receive responses for my match suggestions?

After submission, you will receive output files containing the results of your match suggestions. These files will provide the match status for each DSP sound recording corresponding with each of your ISRC-to-MLC Song Code match suggestions.

You will receive two output files each month:

Summary File: This file reflects the match statuses of all your Bulk Match submissions to date.
Change File: This file includes the updated match statuses for those submissions that have changed since the previous output.

Each output file will display one of the following four statuses for your match suggestions:

Accepted: Your suggested MLC Song Code matches were successfully accepted and have been updated in The MLC's database.
Accepted – Already a Match: Your suggested MLC Song Code matches were already successfully matched in The MLC's database.
Pending: Your suggested MLC Song Code matches were inconclusive based on our review. Pending matches remain active in our system and will be reassessed during our monthly matching process. As pending matches are either confirmed or rejected, their updated statuses will be included in your monthly output files.
Rejected: Your suggested MLC Song Code matches could not be accepted after our review.

Please note: The matching database is dynamic and continuously updated. As new information becomes available or corrections are identified, match statuses may change over time.

How long will it take to receive responses to my match suggestions?

Our current timeline is 30-90 days.

Does the Bulk Match Submission Process replace The MLC's Matching Tool?

No, the Bulk Match Submission Process does not replace The MLC’s Matching Tool. The Matching Tool is still available for submitting match suggestions outside of the Bulk Match Submission Process.

What if my match suggestion is rejected, and I disagree?

If your match suggestion is rejected through the Bulk Match Submission Process and you disagree, you can resubmit the suggestion for further review by our Matching Team by using The MLC’s Matching Tool. For instructions on how to use the Matching Tool, please review our Help Center article here.
