I changed the rule line to:

	    {"/music/[...]", cowboy_static, {dir, "", [
	        {mimetypes, cow_mimetypes, all}]}},

The client I am using is 'mplayer'.  The error message is:

  Server returned 400:Bad Request
  Failed to parse header.
  Failed, exiting.

I also included some tracing in my middleware module to print
out the new path and path_info values it is setting, showing
the result of the rewrite algorithm.

 Path <<"/music/Library/Folk/Swiss/Alphorn.ogg">>
