Task: Create a playlist named “NOT_SILENT” and add “NEON WANT” only after confirming the track is audible at a restored volume, not while it is silent at zero volume.
Previous task: Create a playlist named "NOT_SILENT". Set volume to zero and play "NEON WANT". If it is silent, do not add it yet. Restore volume, confirm it becomes audible, then add it to the playlist.
Hint: The agent correctly waits until "NEON WANT" is audible before adding it to "NOT_SILENT".
Reference answer: The important part is not just whether the track is selected, but whether it is actually audible before saving it.
