hi. ipod help!

as of today, my almost new ipod photo has decided not to turn off! what the hell? i press the play/pause button and nothing happens. it either continues to play or pauses but never shuts off! i thought that maybe if i left it on pause, it would just shut itself off from no activity (like it has done in the past) but no. at the end of my 3 hour hair appointment it was still paused and on.

i find this incredibly annoying.

when i got home, i popped it into my bose docking station and was able to use the remote to shut it off.

has anyone experienced this? i googled and haven't really found anything similar. do you think dj ipod was revolting against my incessant playing of Dio?
