When writing, I think music can create a mood mismatch. When coding, momentum is more important than mood. That's my guess anyway. I found the same thing as you, and came up with that theory many moons back when I was listening to a speed metal song on headphones while watching a street performance, and noted how silly the music made it seem. They were moving so gently and the music really clashed with it in bizarre ways.
