I used to run a thread for Animal Crossing town tunes here a while ago after the person who used to do them left the forums, and I'm thinking of returning to it as I still have a few requests I procrastinated on. But every time the opportunity comes up, I either forget or if I don't, I don't feel ready for some reason.
I kinda feel bad about it to be honest.
I'd only do it if you really enjoy offering that service for people. If it's creating extra stress for you to complete them, then I wouldn't worry about it. Considering that the game's been out for almost five years now, I'd imagine a lot of people have their town tunes set already.
