Songs with violent lyrics can make listeners up to four times more aggressive, according to a new Australian research.

Some heard only backing music, others heard just lyrics with some being exposed to the full songs alongwith their video clips.
The lyrics of these songs included references of raping women, slitting people's throats and pushing babies onto busy streets.
Thereafter, students were asked how much hot chilli sauce they would make a fellow participant eat even as they knew the other person hated spicy food and would have to eat it all.
Those who had not heard the lyrics or music said they would give an average of 3.8g - a small teaspoon - of chilli, while those who were exposed to music without lyrics would give an average of 8g.
However, for those who heard the lyrics, the average was 12.7g of chilli.

He went on: "It's actually very hot sauce and you know if you put a lot (on a spoon), you can really hurt the person.

"It doesn't matter what sort of person you are - it has the same effect.
"I think a (music) rating system that gave much clearer guidance as to the content is going to be helpful."
Warburton added: "I also think it's really important we educate children and parents about the effects - and parents should listen to the music their kids listen to, just to get a sense of what it's like."
