I've just received an email containing my year 2016 in music. To be honest, I am sad that it's not a fancy webpage with more interesting statistics as it was the year before or the year before that one.
But, what I've noticed even from the scarce statistics is that they are incorrect. Most of the data the email contains seems to be either from very specific time range, or incomplete.
As an example, I can see that the day I've listened to music the most is Sunday, which is impossible as I listen to music mainly during the work week, about 6-9 hours a week day.
Another issue are the most popular tracks and bands, where I know the second and third place are artists I've listened to probably 5 or 6 times during the year and I know for sure there are artists I've heard 100+ times.
Spotify, can you explain how are these statistics measured, or if they are final? As they seem very wrong to me :)
