how do you change to another music without switch on the ipod?

I have to buy another ipod nano (6th Generation) because the switch button on top is out of order. This is because everytime when I change/skip music I have to switch on the device first, then after some time, the switch button was broken, it couldn't pop up after I pressed it. Are there another way that I can change / skip music without switch on by pressing the button?

I love this ipod nano and think it's best design ever I had. I have every generation's nano ever since the 1st generation, I wish you could keep the 6th generation in store as I have heard so many negative comments about the 7th generation design...unbelievable disappointment!!!!

Thanks a lot.
