Ten years ago was 2014, there's been a lot of changes to Spotify in 10 years, not even just in types of content (podcasts, audiobooks, music videos) but the whole recommendation system, daily playlists, discovery playlists, lyrics, even banal things like playlists folders didn't exist 10 years ago.

There's also a lot of scaling into new markets they didn't have presence in 2014 (which requires scaling in billing, legal, accounting, etc.).
