AO - Thanks, I've tried with and without 'Shuffle'. Without 'Shuffle', the tracks come up on-screen in the wrong sequence, which is fixed. With 'Shuffle' they play in a sequence which differs from that on-screen.
Bushfiva - Thanks, I've read up on ID3 tags and it is a vast subject quite beyond my limitations. Even if I were able to edit ID3 tags, the prospect of doing this for hundreds of cds sounds like a lifetime mission. I get the same results with tracks auto-ripped by Amazon and tracks ripped with WMP. I was hoping to find an in-Chrome app which is compatible.
