I think the OST is looped. I just checked it, and "Made in the U.S.A." definitely seemed to be. OC Remix has 2 Super Street Fighter 2 things out there; the ReMix project "Blood on the Asphault" and the SSF2HDR OST. Here's the website with the OST on it:

[Sorry if I'm wrong that it's looped. I was honestly only half paying attention, but it seemed that the loop was right in the middle where it should be.]
