I'm using the Curl example to attempt song detection. At first, it was telling me that only .mp3, .ogg, and .wav are accepted and I needed to change the content type to application/octet-stream. 

Once I did that, I got a message saying the following:
{
  "detail": 
	[{ "loc": ["body","file"],
	   "msg":"field required",
		 "type":"value_error.missing"
	}]
}

I'm pretty much following the example verbatim, so any help here would be appreciated.
