  [00:00.52]Abracadabra abracadabra
  [00:03.97]Ha
  [00:04.66]Abracadabra abracadabra
  [00:12.02]Yeah
  [00:15.80]Pay the toll to the angels
  [00:19.08]Drawin' circles in the clouds
  [00:23.31]Keep your mind on the distance
  [00:26.67]When the devil turns around
  [00:30.95]Hold me in your heart tonight
  [00:34.11]In the magic of the dark moonlight
  [00:38.44]Save me from this empty fight
  [00:43.83]In the game of life
  [00:45.84]Like a poem said by a lady in red
  [00:49.45]You hear the last few words of your life
  [00:53.15]With a haunting dance now you're both in a trance
  [00:56.90]It's time to cast your spell on the night
  [01:01.40]Abracadabra ama-ooh-na-na
  [01:04.88]Abracadabra porta-ooh-ga-ga
  [01:08.92]Abracadabra abra-ooh-na-na
  [01:12.30]In her tongue she's sayin'
  [01:14.76]Death or love tonight
  [01:18.61]Abracadabra abracadabra
  [01:22.18]Abracadabra abracadabra
  [01:26.08]Feel the beat under your feet
  [01:27.82]The floor's on fire
  [01:29.90]Abracadabra abracadabra
