I used Spotify briefly on an iPhone 13 Pro and I immediately felt how responsive everything was. Loading playlists, playing a track, searching, loading other types of content. It's shocking how good Spotify's streaming tech is. Then I went back to Apple Music again and I immediately felt how slow and unoptimised everything was in comparison.
From a technical perspective, how is Spotify, which has a 100 times smaller market cap, able to completely demolish Apple in streaming technology?
