Support devel_generate creation of audio nodes

devel_generate.module specializes in quickly creating lots of nodes. ideally could create audio nodes. i would be fine if all audio nodes actually pointed to the same audio file which is already in the filesystem or uploaded on the generate form or whatever. if i try to generate audio nodes now, i get "The selected file /Users/mw/clients/penton/Drupal could not be copied.". the error makes sense. the solution is non trivial. any thoughts? note that devel_generate also wants to create nodes with imagefield and filefield fields. and the D6 version already generates nodes with upload.module attachments.
