Why do I want a pile of .ogg (or .mp3) files? ? Back in the day, having a huge library of files on a disk, a carefully curated collection from which to burn a mix CD to present as a gift to a romantic (or platonic) interest was worth the world. Times have changed though, and that carefully curated mix CD full of mystery - what will the next track bring? - these days it's still just as carefully curated, but it's a link to a Spotify playlist. Music hasn't (quite) fragmented the same way video has, with Netflix, Hulu, Disney, Paramount, CBS, HBO, YouTube and so on all having paid options, but having a spotify account with apps on all devices is just so much easier.
