I wondered whether there was some distinction between listening to music (OK) and playing music (not OK) that would justify the Grand Mufti's actions. As near as I can tell, both listening and playing music are criticized by Mohammud. Also since Mohammud's actions are, per scripture, praiseworthy, they are to be emulated and besides the criticism seems to be divinely initiated.
I suppose that the Grand Mufti's actions could be defended if there were some greater purpose; that is, enjoying the music this one time would help some overarching objective but no such defense has come out. Thus I'm going to have to call this one hypocritical. As for the seriousness, it would seem it isn't trivial because, assuming Muslims aren't supposed to listen to music, the pictures of the Grand Sheik enjoying music would weaken the resolve against music (I'm assuming the Grand Sheik is pretty important). Of course if the entire hadith against music is wrong, then it is the sermon that was a problem and the enjoyment of music actually improved things.
