Meanwhile i changed something on that file and reuploaded it again. So after the first time PA did not detected anything, now it could read Artist and Title. But you can also see, that PA is not displaying the length of the song.
And the Info/Tag Box is not from the song Mountain View. It's another one, called Erased.
Once PA is detecting the metadata correctly, it keeps it. In some cases it just takes some time after adding new music via MediaMonkey, until PA is detecting the metadata.
I can imagine that it have something to do with MediaMonkey, because adding the songs manually is working fine. But i don't know what the problem exactly is.
I will keep that wipe of the card in mind.
