MP3 players in schools

I believe I just solved any classroom management issues; however, my solution goes against school policy and my administration.
Almost all my students have MP3 players. During school hours, no student is allowed to use their MP3 player... to the disadvantage of the teachers and the students. It is silent in my classroom. Nobody is talking. I mean, nobody. About 100% of my students are working, except for apathetic Anthony, who usually doesn't complete work anyways. I feel victorious. I am able to spend time blogging and doing my own writing, while all my students are writing. This is phenomenal and unheard of.
More and more, educators push for technology in the classroom--smart boards, intellipads, computers... and yet, mp3's are dismissed.
Well... the class was wrapping up so I really didn't finish my thoughts. In any case, as long as students are completing work independently, I'm all for individual MP3 players.
