Avatar Soundtrack, Apocalypto Soundtrack

[Payoang]

While it's not new that composer James Horner is both amazing and one with Hans-Zimmer-esque tendencies to copy himself, I found something that made me pause. Most of the Avatar soundtrack seems to be a derivative work from Apocalypto, aside from some Na'vi chanting and an altered motif.

Have a listen! Amazon is the only legal copy of the songs I could find online: Apocalypto Soundtrack. The songs in question are From The Forest... and Frog Darts.

There are some derivations from Terminator 2 and Aliens also which appear during the final battle sequence in Avatar.  I have not picked at it enough, but I suppose he does that a lot.
