complaint about Y.P, my roommates

Dear Y.P.
Hi! I'm your roommate, Sung Se Un. I'm really having fun with you as a roommate, but still, I have a little complaint about you. I think this is a complaint that may of my roommates would agree. You are having too much joy with your songs that are saved in your phone. So we are having a hard time with your action. As a result, we are having stress with you. So, please, stop it! And, you can lower the volume, so don't damage us!
