I have my junk filter set to loose .. almost to the far left, and show junk results at bottom of search results. This is so I can double-check nothing is considered as junk when it is not. And still I get files registering as junk even when they are not.

The song I downloaded is a 'soul' song. Not sure if that's the same song as you were after. I could potentially upload it privately for you to double-check.
