This was the big hit of the summer in our family - a great latin groove and a nice simple chord progression of E and D/E outlining the mixolydian scale E F# G# A B C# D (in the key of C that scale would be C D E F G A Bb - the major scale with a flattened seventh degree.
The guitar riff is played on a nylon-strung guitarlele, which is like a guitar missing the lowest five frets so the tuning is A D G C E A low to high. To recreate on a conventional guitar play the E chord as x7999x and the the D/E chord is this week's chord of the week:
D/E: x7777x
To get the repeating bassline E for a beat followed by B and D for half a beat each you could precede and follow the chord with a B note 7xxxxx and a D note 5xxxxx.
You can see the chord being played on the guitarlele at 1:23 in the video below, except he doesn't really, he just plays a D chord 2 frets down from the E and lets the bassline take care of the E root note. Oh well.
