Have both here, spotify crashes randomly or I just get a blank screen and sometimes requires force stopping the app to make it work at all. I have a phone with an SD card (rare I know) and set in the spotify app to download songs to the SD card, however it randomly switches that option back to internal storage for no reason I am able to discern. I gave up changing this setting after the fourth time as spotify just straight up won’t work for like a week or 2 (done everything except un and reinstall as I don’t want to have to manually re-download all my music (I don’t have everything in Playlist as I usually enjoy jumping from album to album without spotify shuffling the same 3 songs it thinks I love immediately after). I have over 20k liked song but spotify only want to play the same handful of songs makes it really frustrating to use. Spotify also has a really annoying habit of removing an album from the artists page whenever an anniversary or remastered edition comes out. I understand not wanting to have several of the same album listed, but sometimes I prefer the original recording before everything was ‘cleaned up’.

YouTube music is my backup music player for when spotify shits itself, as stated above it usually fixes itself after a week or two The main reason I dislike yt music more than spotify is that it plays audio from videos that are straight up not music. It also plays the outros of videos where artists are talking about the album, thanking you for listening, or upcoming tours (which have already happened since the songs were released years ago). These 2 issues keep me from fully switching to yt music.

Got a cheap mp3 player and micro sd card and use that more than either yt or spotify. No internet required, no ads, no songs getting delisted, no subscription. Just all my music readily available.
