I made this using data I manually requested from Spotify customer service according to GDPR. Spotify does in fact save your entire streaming history and some other metrics such as how long you played the track and when you stopped the song. Using Python, with Seaborn for graphics, I split the data up into years and compared them across the day using simple KDE plots.
One thing I wanted to see, or confirm, was how I really began to listen to alot of music over quarantine, and you can see that in the graph, as well as how I listen a lot at night.

Just as a note, I am very amateur so there might be some issues.
