Disturbers

 
      "Why This Kolaveri Di" (English: Why This Murderous Rage, Girl?) is a Tamil song from the soundtrack of the Tamil film 3, which was released on 30, March 2012. Written and sung by Dhanush, the song was composed by music director Anirudh Ravichander.
A downtempo gaana song, "Why This Kolaveri Di" has been built around a South Indian folk rhythm. Its instrumentation consists of nadaswaram, shehnai, saxophone, urumee and thavil drums, acoustic guitar, and keyboards mixed with electronic synths and scratches. The vocals utilize the singing style of Tamil folk culture. Lyrically, the song revolves around the film's main actor being dumped by his girlfriend; the song is sung by the character in a drunken state, with many of the lines nonsensical.
The song was officially released on 16 November 2011 and instantly became viral on social networking sites for its quirky "Tanglish" (portmanteau word of Tamil and English) lyrics. Soon, the song became the most searched YouTube video in India and an internet phenomenon across Asia. Within a few weeks, YouTube honoured the video with a '"Recently Most Popular" Gold Medal award and "Trending" silver medal award for receiving a large number of hits in a short time.

According to composer Anirudh Ravichander, 3's director Aishwarya Rajinikanth Dhanush wanted a light-hearted song about failed love. Ravichander quickly composed the tune in about 10 minutes
. Dhanush then began work on the lyrics, which he completed in about 20 minutes of playful singing and writing. The first line he sang was "Why This Kolaveri?" which means "Why do you have this murderous rage against me?" The question, however, is not intended seriously.

In a party to The Times of India, Dhanush said: "When I was writing down the lyrics, I kept in mind all the English words that are used in the Tamil vocabulary. Words like I, you, me, how, why, cow. I just framed them into sentences and thats how I came up with the song." Dhanush sang the song in broken English, as a Tamil person might if his knowledge of English was limited. The song is also called a 'Soup' song, where 'Soup' is a colloquial Tamil word which refers to young men experiencing failure in their romantic relationships.
The song was recorded at A. R. Rahman's AM Studios in Chennai. After an early version of the song was leaked to the internet, its creators noticed its popularity and decided to go for an official release.
