DJ Sona fans

I was playing a match with DJ Sona and I asked my teammates if they were listing to Sona's music, I got about 50-50% but that made me wonder, is it possibly to implant something that tells you how many people of listing, just for those random people who like to know random things.

Also, this is going sound strange but, is it possible to implant something so you can mute yourself? Just a random thought there. When I play DJ Sona I try to change form every 5 minutes.
