No way he's doing platinum out the gate
It's either
1. Cataloged as a double album, so it'll get the 2x counting, so if he hits 500k, it'll be marketed as "First Week Platinum"
2. Since it's Apple exclusive for the first week, they'll pull a Samsung/Roc/Tidal/etc. and float the first week with some shady metrics, but won't be transparent about it. This will make Apple Music (and signing deals/exclusives with them) the new plug for artists so Apple can try to dominate Music/Stream distribution.
1 million single album sales first week is Taylor Swift crossover status, not even Beyonce pulls those numbers.
