I don't know. Perhaps these are different songs. I don't know the artists songs so I don't know. Sometimes people mislabel songs & that then gets spread (shared) around so that might be a reason. But notice your search for the title came back with what you were after. Remember an artist search is a general search, but a title search is more specific.

I don't normally use the audio type search. I use Any Type search b/c I find it often brings in results that might not show in an Audio type search. This may include incorrectly labelled titles or artists.
