has anyone who uses their ipod touch on a bose sounddock noticed that the album art goes missing for some albums (never all of it, just random albums)? i recently came across this for a friend, i was able to wipe the music from the ipod, resync the entire library and the album art worked as it should, but a few hours after running the ipod on the bose sounddock, some of the album art went missing again. any one encounter this? would hate to have to delete and resync after every use.
