Hi. In iTunes preferences I just found out from google that there is an option to crossfade songs. If I turn this on and then sync my iPod, will the songs crossfade on my iPod to? Also, If I turn crossfading on and then want to turn it off later, can I do that without a computer? Also, is there a way to set crossfading to only be used on some songs or playlists and not others? Thank you.
