I just reorganised the genres to even things up a bit. I'm now using the same genre types as the iTunes Music Store. Also, a lot of the classification I used is theirs. I'm bound to have offended someone so just click on "report errors" after the title details and I'll fix it. Also, there's still a lot of titles in the "Unassigned" basket.
Thanks in advnace for any assistance in sorting these out.
