YouTube seems to show how many views a playlist has when you view it. This playlist, for example, has 58,878 views.
Does anyone know what this number is made up from?
It doesn't seem to be the total number of views all videos within it have, as one of the videos has over 2.5m views itself. Could it be made up of:
a) when a video is viewed within a playlist, and
b) views on the actual playlist itself (like the link above)?
