Right Round
by Flo Rida

Pretty Simple...

Flo Rida)

Am          C             G           Am
You spin my head right round, right round


Am                  C            G
When you go down, when you go down down


(Kesha)
Am           C           G            Am
You spin my head right round, right round


Am                 C             G
When you go down, when you go down down


This sounds like the right chord progression to me, hope it helps.
