If you look closely, you will see that the m flag was already set to 1. (m1)
All you did was replace the n flag, which will notice to a person instead of msg, with the m flag. So you have the m flag twice now, that's not right.
You also changed the q flag to a g for some unknown reason... there's no such thing as a g flag with /play.
You are what your name means: confused
