ok, so i have a classic 30 gb ipod which is suppose to hold approximately 7500 songs. i have about 6800 in my iTunes library with only one movie trailer in my movies section. when i try to sync my ipod it says that there is not enough space for it to be synced. >_< so, in an attempt i just unchecked a BUNCH of music thinking it would get it down to the 'required space needed.' after that i tried syncing again, it gives me the same error message but it changed the 'required amount' im always like a couple gb's away. its so frustrating!! can someone please help me??!!
