High School Musical 1 Soundtrack sold 4.1 million before HSM2 Soundtrack was released.
HSM1 Soundtrack sold 4.9 mil total.
Given the almost decade decline of album sales, and that 2 more movies couldn't push HSM1 to 5x Platinum why would Frozen 2 push Frozen to 5x Platinum?
+ the Holiday sales will be decent, but nothing amazing. It's a movie from a year ago.
Y'all overestimate errything.
