#1 - I have my 4g 20 gb iPod on a dock. Every once in awhile, it will make a beeping type noise (has kind of a tune to it). It doesn't last long, maybe 2 - 3 seconds. Does anyone know why it does this? #2 - Is there a way to shuffle within a subdirectory? i.e. I'm in artists ---> artist 1 ....and I want to randomly go thru the songs in there. Thanks!
