The GRid is a unique identifier for digital albums. The GRid, which stands for Global Release Identifier, is part of a system that allows digital music files to be identified, constituting the electronic version of the Universal Product Code (UPC).
And why GRid in addition to the UPC?
Although UPCs are effective in tracking the physical sales of specific content, they are not as effective when it comes to songs that are sold digitally.
In turn, the GRid, which consists of a unique code assigned to each digitally distributed content, ensures that artists are rewarded for each digital sale made on the internet.
For now it is not a mandatory requirement to distribute your music.
