Frozen Blu-Ray song rips

I was wondering if anyone out there had already done this or could do it easily. There’s a lot of times in Frozen (and Disney movies in general) where the songs they sing in the movie have subtle themes missing when they put them on the OST. In particular for Frozen, the reprise of "For the First Time In Forever" has a choral cue at the end that’s not on the soundtrack, and I love it. Another major offender is Aladdin…but I suppose we have to wait for the Blu Ray this fall. Anyway, thanks in advance!

Let It Go also has a slight echo on Elsa’s voice in the movie that I think is really lovely.
