Dopamine is a substance brain cells release to communicate with each other.
While Dopamine normally helps us feel the pleasure of eating or having sex, it also helps produce euphoria from illegal drugs.
A new study shows Dopamine is also involved both in anticipating a particularly thrilling musical moment and in feeling the rush from it. A new study, which scanned people’s brain as they listened to music, shows it happening directly.
The study used only instrumental music, showing that voices aren’t necessary to produce the dopamine response
The tie to dopamine helps explain why music is so widely popular across cultures, Robert Zatorre and Valorie Salimpoor of McGill University in Montreal write in an article posted online Sunday by the journal Nature Neuroscience.

In 1894, the Times of London forecast that by the middle of the following century every street in the city would be buried under nine feet of horse manure.
Energy sources change.
