hey guys, my 4th gen 40gb iPod will be off, i'll turn it on, scroll to either a playlist or just an artist and pick a song. i will feel it vibrating in my hand as the hard drive starts up and such, then it will play a different song than the one i picked, and it will say song 2 of however many is in the playlist. i can hit back and it will play the first song, but its pretty annoying as it happens kinda frequently. it happens more so when i havent used my ipod yet that day. any others have a problem like this?
