I did my first transfer of 1150 songs which took an absolute age compared to my previous ipod and I was annoyed to find that not all of the album artwork converted.
I had spent hours and hours making sure all of my itunes database was correct and containing album covers and transferred from there.
I loaded WMP where many of the things I fixed in iTunes are still broken like mistagged songs and incorrect artwork although nowhere near as many as before I began fixing my iTunes database.
I think the headphones that are supplied are brilliant unless I'm in a car or on the bus where the slightest bump on the road results in, not a jump, but a grating sound in the music. Something definitely happens but the sound seems fine if I move the unit around or give it a knock. Could it be the headphones?
So yeah, all the album art isn't transferring over and a transfer takes an age.
