text: And the beat goes on, Im a happy girl
  Its my birthday song, in my happy world
  I know its gonna be a good day
  Oh yeah, today is my birthday, huh
  And the beat goes on 
  Im a happy girl 
  Its my birthday song 
  In my happy world 
  Light my candles, got to make a wish
  Wrap up the present and seal it with a kiss
  Give me a spanking, start the day off right 
  Because its my day, you are going to sing my song tonight
  And the beat goes on 
  Im a happy girl 
  Its my birthday song 
  In my happy world 
  I know its gonna be a good day
  Oh yeah, today is my birthday
  Im a happy girl 
  My type of party, theres no hangover
  So grab your things, you better come over
  We get high and we still stay so-ber
  We throw it down and then we going to start over
  My type of party theres no hangover
  And the beat goes on 
  Im a happy girl 
  Its my birthday song 
  In my happy world 
  I want a diamond, dont give me a fake 
  Ill let you lick the frosting off my cake 
  Give me a spanking, start the day off right 
  Because its my birthday, youll be singing my song tonight
  And the beat goes on 
  Im a happy girl 
  Its my birthday song 
  In my happy world 
  I know its gonna be a good day, oh yeah, today is my birthday
   In my happy world
  I know its gonna be a good day, oh yeah, today is my birthday
  Im a happy girl
