If you haven't tried yet:
open Origin
select Mass Effect 3 from "My Game Library"
from the tab below the play button, select "Extra Content"
scroll down and their should be "Mass Effect 3 Soundtrack" available for download
Not seeing it. Could it be what's labelled as "N7 Collector's Edition Materials"?
No, "N7 Collector's Edition Materials" is a different item, it should just say "Mass Effect 3 Soundtrack".
I am not seeing anything that says "Mass Effect 3 Soundtrack".
Then I would suggest to contact EA directly. (Top bar "Contact Us".) This might be an account issue.
If you are not from the US change the country in the top right corner.
