It just repeats G, C, D, C for the whole song (chorus and verses). Use standard reggae 
strumming.

           G                    C             D
I feel good, when you're wrapped up in my arms
          C
Dancing to a reggae song
G         C         D  C
Feel good, feel good

           G                     C          D
I feel good, cause you're perfume isn't loud
          C
And only I can talk about
G         C         D  C
Feel good, feel good
