I wish YouTube Music did this :(

Ideas for other analysis;

Songs that over or under index when sliced by some other dimension. Weather? Morning vs evening? Weekday vs weekend? Summer vs winter?

Songs you never finish vs songs you always finish.

Songs you don't like from albums you do.

One hit wonders (within your personal taste)

Songs you've played 10+ times but haven't heard in over three years

If you had this data at scale: favourite songs from people who enjoy similar niches to you (it's me! Listen to Televators by TMV).
