statistics for content

There are statistics on this site. However, the statistics are very limited and are only to the depth of how many views, hearts, comments, diamonds and of course downloads a piece of content gets. This is acceptable; however, it does make it hard to tell exactly what people like. I would like to suggest a feature similar to the YouTube analytic system. It would be nice to see WHEN a piece got very popular, as to determine things like what trends have gone and went, or to see what people like in general. Most of this is already able to be done, but it requires math, and it is also sometimes impossible altogether. Mainly I would like to know utilizing a graph when a piece of content was most popular, and be able to easily compare it with other pieces to see what preforms best. If you want to go super in-depth I'd be glad to see even how long the average person stayed looking at a piece. It would be nice to see what your average is of downloads/views.
