The beginning and the rap part is just D A G Bm A G repeated. Throughout the whole song, 
it will be those chords. The only part that I'm unsure of is the techno/instrumental part.

CAPO 1:
             D
I'm on the floor, floor
    A       G
I love to dance
            Bm               A         G
So give me more, more, 'till I can't stand
            D
Get on the floor, floor
           A          G
Like it's your last chance
             Bm
If you want more, more
      A     G
Then here I am


    D            A       G
Starships were meant to fly
 Bm             A        G
Hands up, and touch the sky
  D                  A       G
Can't stop, 'cause we?re so high
  Bm           A         G
Let's do this one more time
    D            A       G
Starships were meant to fly
  Bm            A        G
Hands up, and touch the sky
  D            A         G
Let's do this one last time
  Bm          A          G
Hands up..
