This is a pretty popular concept. I see a lot of it on Tumblr. I picked it myself because I wanted a way to share playlists with my friends while avoiding pushing my particular taste on them. So I decided four playlists in the course of a year (2020) doesn't seem like a big deal. Only I developed a curatorial passion for it. I personally picked the order of the songs in a personal throwback way but made sure that it works on shuffle too. I've only included songs I love. I've known many of them for years but some are new to me and that makes them exciting and worth including.
(I did just find out about this page so please excuse me).
