Still working on my Book/CD/DVD/Blu-ray database, up to 2.5K items now and counting! It’s all in a Numbers spreadsheet, once I’m done I will be exporting it as a CSV and then importing that into Collections. As I have mentioned previously, it’s a super handy app which nicely syncs between the Mac / iPhone / iPad versions.
I recall having a much smaller catalogue of some of my media back in the day using an app called Delicious Library, I bought the first version in early 2006. It was certainly from that magical era of peak skeuomorphism - the app window was a woodgrain bookshelf with all the front covers arrayed across it :)
Currently listening: “Deep House & Coffee Party in Buenos Aires | Mat, Alejo & Lothar”
