Many random files not showing up

Problem:For some time now (I think it started after I updated the server, but I am not sure) various songs do not show up at all. I have files structured as music/artist/album and only a few songs of an album will show up, all in the same folder and same file type so there seems to be no reason for some to not show. Does not matter what playback application I use, the server cannot find them.
