Missing data in download

[kklaliotis]

Hi! I recently downloaded my listening data from the year because I wanted to look at my own yearly listening statistics. There is one artist in particular whom I know I have listened to a lot in the last several month who does not appear in the data table at all. Is the user data I downloaded from Spotify complete or is it a summary? How could it be possible that there are missing tracks and artists?

As a side note, I was hugely disappointed that there's no data on genre included.
Thanks.
