In truth, the Original Soundtrack is linear, meaning there's a beginning & an end, and putting it on repeat has it's obvious breaks. The majority of the In-Game music is edited to loop, meaning that it has no beginning or end and the music keeps going seamlessly without an unintended pause or silence.

This is useful to those who want to use it for video-making (which within Microsoft's Game Content Usage Rules, we can do so), music remixing, or just want to extend their favourite track from anywhere between 5mins or 10hrs.

As the In-Game Music is of a lower quality than the Original Soundtrack as it was compressed to help in making the game smaller in size (Audio takes a lot of space! Infact, 35/50GB of Titanfall's HDD space requirement is just Uncompressed Audio), I put the OST Tracks & In-Game Tracks alongside each other, used the In-Game track to determine where the loop begins & ends, and then simply rendered the OST Tracks with that loop, whilst keeping an "Intro" & "Loop End".

Simple as that.
