Know more about Why This Kolaveri kolaveri Di Song

                     
                   Why This Kolaveri Di  is a song from the soundtrack of the upcoming Tamil film 3, which is due to be released in 2012. The soundtrack and background score is composed by Anirudh Ravichander. This song was officially released on 16th November 2011, and it instantly became viral on social networking sites for its quirky "Tanglish" (Tamil–English) lyrics. Soon, the song became the most searched YouTube video in India and all over the world. 
                
                      According to composer Anirudh Ravichander, the director Aishwarya Dhanush wanted a lofty fresh song on love failure, and he had composed a suitable tune for that. Dhanush, then reportedly came up with this song in around 20 minutes. In an interview 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." According to Dhanush, the song is suitable only for bathroom singers. Its simplistic and rustic beats make it more catchy to the commoner. Heartbreak is a phenomenon almost everyone can relate to. The song was initially leaked to the internet, and the makers, having noticed its popularity, decided to go for an official release.
  
Lyrics :
 
The lyrics of this song is rather simple and is written in the easiest form of Tanglish, a mixture of Tamil and English. The lyrics portray the feelings of an average Indian boy, who has failed in love, or who has some problems with his girl.

Music video :

This song was initially leaked on the Internet, and the makers, having noticed its popularity, decided to go for an official release. The music video features the actor-playback singer Dhanush singing the song in a studio, while co-star Shruti Haasan and director Aishwarya Rajinikanth hear along in the sidelines. Composer Anirudh is at the piano.
