Wouldn't it be great if you could add your own music to all 3 forms of the new upcoming sona skin? I think it would be. I don't know if it is possible to make but it would be awesome! And I'm not sure but i think when a Dj Sona is in your team you can hear her Music but again i'm not sure. But if it is so i don't know how you can make it that your teammates can hear your music too. But anyways i would give it a try. 
Yes that would be a great idea if you could at all trust the community. Some people would heavily abuse this and play MP3 files about how people should kill themselves or using racial slurs, if it was a perfect world that would be a good idea xD
Yeah this would be great. You should be able to have unique settings in which you can copy and paste the youtube link of the song, and it would play the audio for that youtube clip ingame.
overall, i think this is a great idea and i wish it could be reality, but it is doubtful i this wouldn't cause any problems.
i guess, there should be an option to switch to classic music if people troll. That also solves the problem with difference in musical tastes. Maybe there could also be an option to switch to DJ Sona's classic tracks - after all, the music that was written for the skin should be used too. there should also be a list of banned YouTube songs/videos, so that with each troll music, so that each troll song would be permabanned and there would be less and less possibilities to request bad stuff. And if people request something very bad, like extremely loud screamers, ultrasound, racist/sexist/hate songs, porn moans and etc., they should be reported, so there should be another reason for the report added, but only if the player was playing with that skin. i think that people would still write: what an awful music! Your music sucks! - and stuff like that, which is toxicity... and should be reported too.
