Quarion Nailo, prepare yourself for the highest praise the cosmos knows how to give. Here it comes:
Having just discovered this thread, I played Head to Head. My fifteen month old baby was about ten feet away playing with some blocks. As soon as Roy's theme started he looked over his shoulder at the speakers, totally entranced. When Thog's theme started, he stood up - still totally entranced. When the two parts joined together, he started bouncing up and down a little. The bouncing got more and more energetic and happy so that by the time Thog Rage started he was full on dancing around the floor.
It was awesome.
As is the song.
