time after time after i add one new song to my library, even though i have plenty of space for it, itunes will say there isn't enough room in my library to hold all the songs and wont sync the song. for instance, i just added a 4.3 mb song to my library. i have 70mb free space. itunes is saying i need 696.5mb free space in order to sync. are you joking? this happens over and over and over... any ideas? EDIT: i just unchecked that new song so it wouldnt sync with the phone and itunes says the same crap, only it needs 691mb...which is the number from before minus that song. i havent checked anything extra, there are no videos, podcasts, nothing that i dont know about getting synced. as of yesterday i could sync now i dont have enough space...its bogus. i've looked a billion times. frustrating!
