As a measure of how little the underlying music means on Discogs consider: Users do not need a record, tape or CD player to make a submission. The only requirement is having the physical media in one's current possession.

All 'music' data is transcribed from the media jacket, labels, matrix stamps &c by the users. Management doesn't upload anything... except one-at-a-time via their individual user accounts just like me.

The common practice of transposing mechanical rights for 'writers' means lyricists appearing on instrumentals and other musical oddities.
