Requirements Gathering: Histogram of Playlist Sizes and Histogram of User Playlists Quantity

[userdk]

Hello, in order to help understanding questions and insights related to an app's scale and query volumes, it will be very helpful to see a histogram of the number of songs in each playlist. Likewise, having a histogram of the number of playlists for each user.

In addition to those 2 histograms, I am thinking a 3rd histogram that will be useful is one that conveys statistics of a playlist size and how often at least one song from it is accessed. One purpose of this histogram is to figure out if playlists with many songs are actually accessed a lot, or asked another way: Is a large playlist used a lot? (Since a large list may exist frequently enough, but never be used, and one can conclude the risk of API limitations when querying it, etc. may not be warranted to support in an app.)

The main market of interest is US/North America.

Some questions I am interested in having answered via the histograms are:

1) How many songs are typically in a playlist?

2) How many songs in a playlist would be a typical amount if the playlist is large?

3) What percentage of users have large playlists?

4) How many playlists does a typical user have?

5) What is a typical quantity of songs in a playlist if it is considered to have many songs but still somewhat encountered?

6) Given a playlist size (or size ranges), how often are songs within it accessed? (Does interaction with playlists trend downward as the playlist size increases, and what would be considered the cutoff?)

Thank you.
