I might be having rose tinted spectacles but I remember when Spotify first launched in the UK, maybe 2010. The app was _screaming fast_ in comparison to iTunes at the time, and I think it had a similar interface to itunes as well (although could be misremembering) with a table-like layout [1]
I really don't understand what happened between then and now, it was really a big deal at the time where the UI was snappy and playing a song was almost instantaenous. Nowadays, while the playback speed is still just as snappy, the UI feels much worse
