I will try to explain again..
suppose I have an album that was ripped through jriver. the name of the artist for example is a. when i will use tagging and change the name for b (on jriver - I know it doesn't change the true file name ...), the album will move to the be the first album in the "b" letter after all the albums starting with "a". it does not happend to albums that was ripped with other software - there the name of the artist under the picture of the album refuses to change and move... it is importand to me because i cannot organize all the albums of the same artist together if the spelling of the artist that was ripped with other software isn't identical by 100%...
