Re: The software has issues but still a user error
Windows Media Player is nearly as bad. Several times I have spent ages carefully populating the metadata of an album's tracks only to notice shortly afterwards that some of the tracks have disappeared.
Hunting around often locates the file, badly renamed, in a folder created by WMP called something like "uvva muusik\best traxx in worrrrdl eva", and with the metadata stamped over with something irrelevant which uses the wrong case for every letter, even where a real word appears.
Apparently, Microsoft employ people with this level of language skills ( scyllz ??). The people who ring you pretending to be "Windows Technical Support" do better.
