The heart is a myogenic muscular organ found in all animals with a circulatory system (including all vertebrates), which pumps blood throughout the blood vessels by repeated, rhythmic contractions. The term cardiac (as in cardiology) means "related to the heart" and comes from the Greek καρδιά, kardia, for "heart".
The vertebrate heart is principally composed of cardiac muscle and connective tissue. Cardiac muscle is an involuntary striated muscle tissue found only in this organ and responsible for the ability of the heart to pump blood. The average human heart, beating at 72 beats per minute, will beat approximately 2.5 billion times during an average 66 year lifespan. It weighs approximately 250 to 300 grams (9 to 11 oz) in females and 300 to 350 grams (11 to 12 oz) in males.
In invertebrates that possess a circulatory system, the heart is typically a tube or small sac and pumps fluid that contains water and nutrients such as proteins, fats, and sugars. In insects, the "heart" is often called the dorsal tube and insect "blood" is almost always not oxygenated since they usually respirate (breathe) directly from their body surfaces (internal and external) to air. However, the hearts of some other arthropods (including spiders and crustaceans such as crabs and shrimp) and some other animals pump hemolymph, which contains the copper-based protein hemocyanin as an oxygen transporter similar to the iron-based hemoglobin in red blood cells found in vertebrates.

Afrika Bambaataa (born April 19, 1957) is an American DJ from the South Bronx, New York who was instrumental in the early development of hip hop throughout the 1980s. Afrika Bambaataa is one of the three originators of break-beat deejaying, and is respectfully known as the "Grandfather" and the Amen Ra of Universal Hip Hop Culture as well as the Father of The Electro Funk Sound. Through his co-opting of the street gang the Black Spades into the music and culture-oriented Universal Zulu Nation, he is responsible for spreading hip hop culture throughout the world. On September 27, 2007, he was nominated for induction into the Rock and Roll Hall of Fame.
Afrika Bambaataa grew up in The Bronx River Projects, with an activist mother and uncle. As a child, he was exposed to the black liberation movement, and witnessed debates between his mother and uncle regarding the conflicting ideologies in the movement. He was exposed to his mother's extensive and eclectic record collection. Gangs in the area became the law in the absence of law, clearing their turf of drug dealers, assisting with community health programs and both fighting and partying to keep members and turf. Bambaataa was a founding member of The Bronx River Projects-area street gang The Savage Seven. Due to the explosive growth of the gang, it later became known as the Black Spades, and Bambaataa quickly rose to the position of warlord. As warlord, it was his job to build ranks and expand the turf of the Black Spades. Bambaataa was not afraid to cross turfs to forge relationships with other gang members, and with other gangs. As a result, the Spades became the biggest gang in the city in terms of both membership and turf.

Genres: Comedy,Where is your soul?
buried in all that was
calling your name
every end has a start
tearing as we fall apart
calling your name, calling your name
it's the light on the grave
the wind when you sway
said all you could but you won't make them change
care and you will live
share and you'll be comforted
with all you have to give
sparingly take
but love, love me with all your heart
and i will be brave, i will be brave
it's the light on the grave
the wind when you sway
said all you could but you won't make them stay
stay with me tonight
stay with me light
