soooo.... cause someone was playing music and it was upsetting you, you decided 2 break the server rules? your logic is flawed. as he shouldn't have been spamming music, you were in no position 2 start griefing him and breaking server rules... regardless of the circumstances...
you do have the option of player muting him, not sure why you wouldn't have just done that and waited for an admin 2 log on so it could be taken care of properly.
