It plays over and over on repeat, as if the "loop" button got stuck on your music player. Scientists think of these annoying sound segments as "ear worms.
The songs that get stuck in people's heads tend to be melodically and rhythmically simple, says Daniel Levitin, a psychologist who studies the neuroscience of music at McGill University in Montreal, Quebec.
It's usually just a segment of the song, not the entire thing from beginning to end.
A common method of getting rid of an ear worm is to listen to a different song -- except, of course, that song might plant itself in your thoughts for awhile. In rare cases, ear worms can actually be detrimental to people's everyday functioning, Levitin said.
There are people who can't work, sleep or concentrate because of songs that won't leave their heads. They may even need to take the same anti-anxiety medications given to people with obsessive-compulsive disorder, drugs that relax the neural circuits that are stuck in an infinite loop.
How we evolved to remember music Given how easily song snippets get stuck in our heads, music must be linked to some sort of evolutionary adaptation that helped our ancestors. Bone flutes have been dated to about 40, to 80, years ago, so people were at least playing music. Experts assume that people were probably singing before they went to the trouble of fashioning this instrument, Levitin said.
In Judaism, the Torah was set to music as a way to remember it before it was written down. Levitin points out that many of our ancestors, before there was writing, used music to help them remember things, such as how to prepare foods or the way to get to a water source.
These procedural tasks would have been easier to remember as songs. Today, we still use songs to teach children things in school, like the 50 states.
What about remembering how to play music? When you sit down at the piano and learn how to play a song, your brain has to execute what's known as a "motor-action plan. And you rehearse those motor movements over and over, strengthening the neural circuits the more you practice.
But musicians who memorize how to play music often find they can't just begin a remembered piece at any point in the song.
The brain has a certain number of entry nodes in the motor-action plan, so you can only access the information from particular points in the song. It's the part of the brain that tells us if things are valuable, or important or relevant to survival, said Robert Zatorre, professor of neurology and neurosurgery at Montreal Neurological Institute.
One brain structure in particular, called the striatum, releases a chemical called dopamine in response to pleasure-related stimuli. Imaging of the brain can reveal this process is similar to what happens in your brain in response to food or sex.
But unlike those activities, music doesn't have a direct biological survival value. Musicians can't see inside their own brains, but they're aware of moments of tension and release in pieces, and that's what arrangers of music do. Zatorre and colleagues did an experiment where they used whatever music participants said gave them pleasure to examine this dopamine release.Impact Music Channel IMPACT FIRMAN - Channel.

Since the beginning of his career, Elvis Presley has had an extensive cultural impact. According to Rolling Stone, "it was Elvis who made rock 'n' roll the international language of pop."Rolling Stone encyclopedia of Rock and Roll describes Presley as "an American music giant of the 20th century who single-handedly changed the course of music and culture in the mids.".
Music plays an important role in the socialization of children and adolescents. Popular music is present almost everywhere, and it is easily available through the radio, various recordings, the Internet, and new technologies, allowing adolescents to hear it in diverse settings and situations, alone.
