Vevo was unable to retrieve data from the YouTube API for several channels due to some changes in the YouTube API’s system.  Those channels have been unable to aggregate the YouTube counts each day, making the totals for those artists seem to stagnate starting somewhere in the second to last week of March.  In the past week, we’ve seen those channels update their total play counts to the expected amounts and resume normal behavior, but the changes are rolling.  When those channels resume, the delta for that day will be an unusually high spike as all of the counts that would have come in over the lapsed period show up in a single day.
