Considering Disney is pretty much buying up (and surviving off of) other existing franchises and putting out very little original work these days, I would almost be willing to argue Disney is copying other works instead of the other way around.
Regardless...the "lightest", "happiest" chorus on D/T is easily Barstool Warrior. Dominant chords in there are F/Fm to C Major, which has to be the happiest-sounding chord known to mankind. The chorus is pretty, it's glorious, and it almost strikes me as odd (ironic?) since the lyrics suggest something darker.
But is it flat out "Disney"? Um no, just no.
