Why This Kolaveri Di (Tamil: வொய் திஸ் கொலவெறி டி, Voy Tis Kolaveṟi Ṭi ?; English: Why This Murderous Rage, Girl? is an Indian song from the soundtrack of the upcoming Tamil film 3, which is due to be released in 2012. Written and sung by actor Dhanush, the song was composed by music director Anirudh Ravichander.
A downtempo dance gaana-ballad song, “Why This Kolaveri Di” has been described as “genre bending” by critics, built around an ancient 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 protagonist 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 it 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 honored the video with a Recently Most Popular Gold Medal Award for receiving a large number of hits in a short time
