A Comparison of the 2 Different "The Force Awakens" Soundtracks, Part 2

FYC Track 2: The Attack on the Jakku Village Part 2

0:00-0:15 = not in OST
Incidental tremolo high strings with low hits.

0:15-1:34 = OST track 1, 5:03-6:23 OST
Not identical (horn parts are little bit different between 0:33-0:35 FYC and 5:21-5:26 OST; 0:50-0:54 FYC is omitted in the OST; and there are a few extra seconds from 1:04-1:08 in the FYC that are not on the OST), but certainly comparable. Presumably one is a revision of the other - maybe the film needed a few more/less seconds in particular spots, so Williams had to add/subtract a few measures from the original. Which is the original and which is the revision is impossible to tell until the film is released and I can study the actual soundtrack in great detail.

1:34-1:53 = not in OST
A little bit more of a tail to the track than in the OST. Mostly incidental bass rumbling.
