Vinyl & Data

In Discogs each release has one or more Format fields, in which a contributor has to indicate what format a device has, or what formats a device has, in case it has multiple formats. I simply looked at all the releases in the database and simply counted, and this is the list I got (from most releases to fewest releases): Vinyl: 4,819,258 CD: 2,913,785 File: 917,569 Cassette: 647,604 CDr: 386,541 Shellac: 146,494 DVD: 85,475 Box Set: 52,634 All Media: 29,217 Flexi-disc: 20,814 VHS: 18,674 8-Track Cartridge: 15,206 Acetate: 9,580 DVDr: 8,581 Lathe Cut: 8,023 SACD: 6,380 Reel-To-Reel: 5,022 Blu-ray: 3,705 Laserdisc: 3,077 Memory Stick: 1,701 Minidisc: 1,613 Edison Disc: 1,308 Cylinder: 1,290 Betacam SP: 1,060 Hybrid: 1,012 Floppy Disk: 1,003 Blu-ray-R: 674 CDV: 601 4-Track Cartridge: 593 DCC: 397 Pathé Disc: 367 U-matic: 362 Betamax: 263 DAT: 209 PlayTape: 144 Microcassette: 135 HD DVD: 65 MiniDV: 57 UMD: 51 VHD: 40 SelectaVision: 37 Tefifon: 3...

Time to dig a bit deeper into the tracklistings, as I believe there is a bit more to the story than what I wrote about in an earlier post . One thing that I kept wondering about is: is this mostly a problem for vinyl releases or for cassettes? I adapted my scripts to also output the format so I can answer this question. As an extra I also checked for shellac records and 8 track cartridges, which also have sides. My scripts found 944 shellac records that possibly have a wrong tracklist. There are even more 8 track cartridges than shellac records with a possible tracklist issue: 1144. This means that the total amount of releases I found with possible tracklist problems is now 148,013. The shellac releases with possibly wrong tracklistings are distributed over the data as follows: Distribution of shellac records with a possibly wrong tracklist in the Discogs data. For 8 track cartridges it looks like this: Distribution of 8 track cartridges with a possibly wrong tracklist...
