Ever since a few months ago, i have noticed that my 4gig 2nd gen nano will turn on randomly after i have turned it off and locked the scroll wheel. It will turn on and play and most of the time go unnoticed if the volume is turned down. I cant even shut it off unless i unlock the wheel and turn it off again. It may be linked to another problem ive had recently, where no matter what song im listening to at the moment, it will go back to the first song on the ipod in alphebetical order by band name, and play it. I can then switch to whatever song i choose, but it happens fairly often. I know its a problem because my first 10 songs have about 3 times the plays as my regularly played tracks. I wanted to know if anyone has heard anything like this, and how i might fix it.
