How Does It Work?

Just upload a file and we will do the hard work of surfacing the rights information.

Step One

Upload your .CSV or .TSV file and include information such as: Song Title, Artist and ISRC.

Step Two

We will ask you to ensure the headings in your data file are displayed correctly.

Step Three

Your file will be processed and matched.

Step Four

Your report will include songwriter, publisher and US mechanical share information.

Want To Know More?

On average it can take someone a whole day to manually match data for just 80 songs, so instead of taking 12 days to find 1,000 songs, you can get your results in just one minute.
