Ok wojee, I couldn't find it on the interwebz, so I took a shot at it.
Funk songs are sometimes hard to pick out chords for because the guitarist often uses a lot of muting so it's hard to hear what he/she's doing, but having said that, here's my take on it.
The verses are entirely variations of E chords. No changes except for some work on a couple of the strings while continuing to play E. You can get the riff a couple of ways:
> e:0-0 B:3 e:0-2-0
Keep playing that until you get to the bridge at 1:04. At that point alternate between C#m and A three times and then on "(girl I) WANT", play a C on "want".
Then go back to funkin' out with the E.
Between 1:45 and 2:33, I got nothin. After that, they finish on the funky E stuff.
Good luck, and welcome to the forum.
