Here's what I found on reddit:
The consensus there is: maybe? I only have 7800 minutes played. It seems too low. Anyone know for certain or have any anecdotal experience on how 2017 WrapUp works? Do your numbers add up?
Another peculiarity is that it says I only 'explored' 5 genres, and lists my top 5 different variations of rock. But I have a few rap songs, reggae and chill step in my top 100. Does explored 5 genres mean listenned to 5 new genres in 2017 vs 2016?
