my ipod is perfectly fine but for maybe a few months, I realize a very few songs I have skip after being played for 30 + seconds. I restore my ipod and also try redownloading the song and it still does it. I'm not sure why it does this to that one particular song. Is this normal, anyone experience this? Apple said they will replace it with a refurbished one and get a 90 day warranty... are refurbished reliable. anyone has a refurbished one because of a replacement and is still lasting good. THANKS and HELP!!!!!!
