Novita Dewi Marpaung was AMAZING!

The best in my opinion :

1. Halo (Beyonce)

head to head against Beyonce

2. Try (Pink)

Head to head against Pink

3. Di Belakangku (Peterpan)

Head to head against Peterpan

however, the x factor is a "X" factor, we are waiting the final winner base on "X" factor, Novita Dewi or Fathin Sidqia? incidentally, both of them showed us the "X" factor in their songs,  lets wait :D
