custom field suit new post with in custom fields

My method for this would be:

  1. Create custom post types for Albums and Tracks, using either the
    Custom Post Type UI plugin, or just declaring them in
    functions.php (it’s not that hard).
  2. Use the Advanced Custom Fields (ACF) plugin and create a “Relationship” field. You can restrict it to appear on Albums, and to accept only Tracks. The interface will allow you to order them by drag-and-drop.

PS: the CFS plugin seems to do pretty much the same as ACF. But I’m more familiar with the latter, so that’s what I would use.
