Rhythm Cleanup

After Rythm commands are sent in chat (e.g. !play, or !skip,) the bot waits for Rythm to reply and then deletes the corresponding number of messages. For example, when !skip is sent, Rhythm will reply with either "Skipped," or "You have to be in a voice channel to use this command." After Rhythm replies the bot will bulk delete the last 2 messages, as if the command never happened. With commands such as !queue, the command will be deleted, however the reply will not. I've never programmed anything before, so the method is not optimal, and problems do often occur. Help and feedback are greatly appreciated.
