liftarn,
I get no song match when I upload "Wolf Heath", which is what I'd expect since we have not ingested that song from any of our partners. Can you post the response you are getting?
The Blondie mashup has enough in common with the original that I'm not surprised that's a match. We try to make a best guess on track/upload identification since the tracks can be encoded and distorted in 1000 different ways.
