I requested the track this year from Peter as I ran into him 1h or so before he set, didn't manage to squeeze in this time around. I requested it from Kandi but it didn't either. That was a sure fire sign that the track was dead, but if it goes the route of a solo effort it might see the light of day in the end!
As for why Peter played it so often - Brandt is no longer DJing, and Kandi is DJing very little. Peter and Brandt always were close and did a few collabs, and since he DJs the most out of the three it's only normal he took it out for a few spins.
