Ditch the iPod headphones. Actually don't even test it, and sell them without opening it.
They are rubbish, but some decent headphones.
you can select all the songs from one album at once and change the ID3 tags in a batch sort of way.
if they still dont match up go along all the tabs and fill in where it says artist/album/composer on the other tabs, works for me.
looked at the white ones and there only £12.49, and there the same part number just diif colour?
