ok reno, i see what you mean about the albums not in A-Z order, please put the problem in bug reports and I will get our Bry to have a look at that...
As for the duplicate albums, I think it will be a case of different spelling in some of the tracks, like spaces at the end or beginning of R Kelly so it creates 2 albums, like these 2 are not the same "R Kelly" & " R Kelly", the second r kelly has a space at the beginning, have a look at the r kelly tracks album tag.
if you cant sort the duplicate albums just let me know and I will take a look for you remotley tomorrow.
