According to The Washington Post, researchers have proven that listening to the music we like causes the brain to release large amounts of dopamine, a chemical that sends "feel good" signals to the rest of the body and plays a role in both motivation and addiction.
The small study, published last month in Nature Neuroscience, used brain scans to show that college students released significantly more dopamine when they heard their preferred music (which ranged from Beethoven to Led Zeppelin to the Israeli trance band Infected Mushroom) as opposed to someone else's tunes.
The researchers think that this may explain why music plays such a significant role in every culture and why -- much like a drug addict's fetishization of their drug apparatus -- people continue to buy better speakers, concert tickets or iPods, despite their exorbitant costs.
