This track in D has a Tex-Mex feel. That means we have a syncopated bassline and Latin percussion. The progression has a couple twists and turns: We use a VII to get back to our I. That would be a C# chord to D. Another chord that's outside key is a iv chord. The progression usually goes in this order: IV-iv-I. That's also how it appears in the track.
