You could probably implement hook_node_view in a custom module. Which will operate on all views of a node.  Test on the type of the node variable and add the appropriate .js files?

Subject: [support] Avoid sub-theme

Hi Folks,

I've added JavaScript/AJAX to a node display which is managed by Display Suite.  Consequently, I've added:

drupal_add_library('system', 'drupal.ajax');
drupal_add_js(drupal_get_path('module', 'music_display') . '/music_display.js');

to ds-2col-fluid--node-music.tpl.php  This works well because the JavaScript is only loaded for this content-type, but it only works because I sub-themed Bartik on this development site.  On the production site, I don't know what theme the designers will use, so I want to move these two line to a module.

How do I create the same qualification, meaning make the above two calls only in the case where Drupal, in the guise of Display Suite, is displaying the "Music" node?

Chris.
