I mean fair enough, i use this version of Spotify and don't pay them a single cent: https://bestforandroid.com/apk/spotify-premium-mod-apk/
But if I was a paying customer i would be pretty pissed opening Spotify the first time on my 3 week travels and seeing this crap :-O Funnily there isn't even an option to change the location as suggested. Neither in the modded app nor on spotify.com on FF mobile.
Never used Spotify, but I got into Apple Music after learning it supports lossless. It’s been fantastic. I have MP3s on my phone and none of them have been overwritten with clean versions or anything like that other guy said… I dunno his setup though. I keep my giant MP3/flac collection on another HDD, backed up to an external.
