That conclusion can no more come out of this research than could the idea that listening to music is an illness.
It probably is, at that.
Both religion and music might have conferred evolutionary net advantages at one point, which explains the existence.
Both music and religion might have served to keep bands of nomads together, increasing survival chances through mutual protection.
The rhythm part of music might also have served to increase our mobility, adding the ability to pace. That we prefer tempos in the range we do is notable.
Harmony might be a side effect of our brains greatly enhanced pattern recognition abilities.
However, the negative side effects of music appears to be far less severe than those of religion. There seems to be little advantage to curing music. While it's still part of being human, I'll gladly succumb to it, because it gives me pleasure with few negative side effects.
