iTunes (or any other player) could display hundreds or thousands of songs in a single playlist and would happily sort them or filter them instantly based on tags or whatever. Spotify, everything is lazy-loaded and I frequently get random elements just failing to load, or the entire player even crashes (like, at least every other month.) And, I know I say thousands but I get this sort of behavior in Spotify when I've only got like ~50 songs in a playlist. And of course it can only do rudimentary sorting/filtering based on tags.
