I can't be the only one that did that science experiment as a kid, looking at The Effect of Music on Seed Germination and Plant Growth. I had a control group, a classical music group, and a heavy metal group. Each group of music assigned plants was subjected to an hour of their music per day, and germination/sprouting rates and subsequent plant growth measured. The plants subjected to classical music germinated the quickest, and experienced a statistically relevant greater amount of growth by the end of the experiment period. Clearly, something is there in the response mechanism… Intelligent maybe? (…intelligent prefers classical over heavy metal? ;) )
