Because as much as the app sucks the everything else is better than everyone else's music app, at least here in India where we have Apple Music as well. Recommendation, organisation, playlist - it feels like Apple Music is doing all that for a different species altogether. Now I already have said how bloated Spotify iOS app is and I still take it any day over Apple Music's native app. Hell, there are flows in Apple Music that has never gonna past a click at certain page whenever I've tried (that's quite a few in times in last few years). Esp. flows around which they try to play with iCloud and social aspects. Hell, I can't even decide what not to see on my Apple Music home screen. Sometimes I've to do few sipes to reach what I am looking for. Even with all the bloat Spotify never tires me like that.
