Does anyone know why some of my albums play correctly (ie in track number order) when using MCE & WMP but some decide to play in alphabetical order of the artist? They are all numbered corrrectly and their filenames all start with the respective track number. If I look at my library in WMP the afffected albums appear in alphabetical order although no fields have been selected. If I click on track number it puts them into the correct order as expected. If I close it down and re-open it, it reverts back to listing them alphabetically. This only happens on a small number of albums. Any ideas?
