Thank you! You helped me a lot with this information. Based on the formula, I can find out the total number of minutes that all users listened to. I saw on the site section Dashboard which shows the active number of users. But, as far as I understand the counters there are not working correctly, since it always shows that there are 51 users on the network. I thought that the information about the points of each individual user is displayed somewhere, I just can not find it. Apparently I was wrong and the developers did not foresee such an opportunity (a similar TOP would create a spirit of competition between users).
