* SetAttribute() will fail for read-only volumes.
* Duration() is called in playlist's Draw() method.
Since _CalculateDuration() is very expensive because it parses
file metadata, it causes visible drawing glitches and playlist is
almost unusable.
* Mitigates #15221. I don't consider this a fix because first draw
is still going to block for a long time, but at least scrolling
works smoothly now. Ideally, file metadata would be parsed
asynchronously in a separate thread and drawn as it becomes
available.
