Required metadata from record labels
- Purchases from Google Play may contain a unique identifier embedded in the metadata of digital download files that is required by some record labels of all companies that sell downloads of its music.
- Google may insert that metadata for already-made purchases, and into purchases that you make in the future.
- The metadata typically consists of the following:
- a random number generated by Google using an algorithm to encrypt another algorithmically generated number that identifies the transaction for the purchase of that file
- an identification of Google as the music store distributor
- Google's digital signature, datestamp and/or timestamp of the purchase industry codes identifying the sound recording
- a digital indicator of whether the file has been modified
