hey!  i really wanted to play this song on the guitar when i first 
heard it.  i think these chords are 99% correct but i couldn't figure
out the plucking part at the beginning & after the first chorus so if 
someone could help with those that would be great!  btw you need a 
capo on the first fret.  enjoy! =)

Chords used:
Em:022000
Am:002210
B:024400 (it's different but it sounded right to me, try it)

for this part you strum the chords once

Em
The weekend's almost done 
                       Am
The moon is low in the sky 
                                            B
Feel like going out before the night passes by
             Em
I won't just sit around 
     Am             B
When life becomes a drag

I dance

listen to the song to get the rhythm for this part

Em-----Am-----B

           Em
I like the bass (turn it up, turn it up, turn it up)
           Am
I like the boom (turn it up, turn it up, turn it up)
       B
I need guitar (turn it up, turn it up, turn it up)
            Em (strum once then immediate palm mute)

Am
Grab your girlfriends, grab your boyfriends, sweat it out
      B

To much rock for one girl can make her go crazy
I need someone to dance with me baby (dance)

            Em
The music's on (turn it up, turn it up, turn it up)
