Ask HN: Given a Spotify playlist, I would like to get all the tracks as MP3s

Some backstory, I got tired of streaming services, particularly Apple Music constantly slapping DRM on top of my own music (ones I have uploaded to iCloud from CDs). So, I was thinking of writing some script that would perhaps get a playlist, be it Spotify or Apple and then get the Mp3 version of that song by whatever means. This is to literally just store an offline version of my music collection and listen to it from there. Any solutions you use already before I go down the rabbit hole of writing my own?

TIA
