Cannot Remove Tracks that have been played from a Crate

Tracks in a Crate that have been played cannot be removed from the Crate. I have not tested whether or not this holds true if you play the track from the Library but try to remove it from a Crate that it is in.

Steps to reproduce:
  1. Add a Track to a Crate
  2. Go to said Crate
  3. Double click or Drag the Track to a Player
  4. Right click the Track's listing in the Crate
  5. Click on 'Remove' in the Track's Right Click Menu

Expected Result:
  Track should be gone

Actual Result:
  Track stubbornly remains right where it is. It also refuses to let it's rating be changed.
