Still can’t quite envisage these high-output YT guys utilising ‘temp’ tracks in their vids with the intention of replacing it with a purchased version. Yet I can perfectly imagine them urgently needing something to fill a segue and popping over to AJ to grab a quick, free downloadable preview - knowing full well that a rapid 4 second ‘blast’ of music won’t trigger any YouTube claims and prevent monetization.
Bear in mind however, I’m basing this practice purely on the countless comments left of my own YouTube channel where people have been encouraging other users to do this. I’ve lost count of the amount of times I’ve had to set them straight. That said, I’d like to think that Mr Pie has made a genuine error here.
