A YouTube video (that the algorithm loved) about all this and is super interesting: https://youtu.be/wyYAiU4DKUY?si=CpcOuhzAvXs7fqWF

Interesting watch. It leaves some things unexplained though. How did Prydz end up as the artist on a song not in his own style, nearly identical to two previous artists making the same song, based on a re-recording of a sample? I wonder if the label was simply looking for a competent producer to make a version of what they thought would be a hit after having figured out how to clear the sample.

You've got it exactly right. The people at the label knew the loop of Call On Me was sure to be a hit. They only needed another version.
