UMG Watermark, true or false?

I visited the Matt Montag site a while back and spent a few hours trying to discern the watermark.

Now I’ve queued up the first track in the Tidal Playlist: “Cry To Heaven” by Elton John.

What am I listening for? At what instant in this 4:17 song does this artifact become most prominent?

Not a skeptic but a student. Please, somebody educate me on this.

Thanks.
