Vinyl
Vinyl albums are by far my favourite physical music media to collect and listen to (which you should be doing with your collection!).
CDs
I have tons of doujin music CDs in a separate spreadsheet, but I do also have a small amount of non-doujin that I like to track separately. These are fun and cheap to pickup while out and about, and still a good way to support modern artists whenever they put them on sale!
Cassettes
I typically only pick up cassettes while out thrifting and if I see something I like.
8-tracks
While not my favourite physical medium to listen to music in, I do still love collecting and have gathered a small amount of 8-tracks.
Floppy Disks
I really love retro computing hardware, so when I saw some floppy disks on sale with music I enjoyed I had to pick them up. I only have two but it wouldn't be a complete log without them.
There's plenty of links on the spreadsheets (mostly to Discogs to further log) to get more info on the artists! There should be a link to the individual release owned as well should there be a Discogs page present. I also keep a small log of previously owned vinyl.
