@SiennaAViolin  about your initial Party room posting:

To start a party in the party room, your posting has to have a theme in which your posted video needs to fit under.  Ideally, you want your party to be inclusive—that is, you want others to be able to join in with a video of their own that fits under the theme you created. 

Perhaps you can think of a broad category (theme) in which your Küchler piece fits (for example, composers whose name starts with a "K", or songs by a German composer, etc.,).
