Specific sounds for each person

One of my biggest problems in discord is, when me and my friends are in a call (almost all the time playing so we can't check the app instantly), someone joins the call and we can't know who it is. So i suggest a function that, in a server, each person has a different sound for joining the call and disconecting. This songs would be chosen by the person, and since the app has partnership with spotfy, the person could choose a song from spotfy for it's ring
