The soundtrack album and background score of Osthe was composed by S. Thaman, in his first collaboration with Silambarasan and Dharani, replacing the latter's usual collaboration with Vidyasagar, who earlier composed his previous films. Silambarasan revealed that composer Yuvan Shankar Raja, who he generally collaborates with, had suggested to sign Thaman as the music director.[28] The music rights were acquired by Sony Music.[29] The soundtrack was initially planned to be released on 6 October 2011, coinciding with Vijayadashami,[30] however the audio launch was held on 28 October 2011,[31] at Chennai. The event was attended by the film's cast and crew and other celebrities.[32] Actor Vijay, who previously worked with Dharani in Ghilli (2004) and Kuruvi (2008), was invited as the chief guest and unveiled the audio CD of the film.[33]

The soundtrack album features five songs, with lyrics being written by Vaali and Yugabharathi, while Silambarasan penned the lyrics for the song "Pondaati". About the song, Silambarasan revealed that the song is revolved around a "husband's praises for his wife."[34] This song and "Neduvaali" sung by Rahul Nambiar and Mahathi, has been reused from Thaman's own compositions from Telugu film Mirapakaay (2011). The equivalent version to the chartbusting "Munni Badnaam Hui" from the original was named "Kalasala".[29] Shruti Haasan was reported to have rendered her voice in "Kalasala",[35] but the rumours were denied and instead veteran singer L. R. Eswari had sung the song.[36] Elements of "Kalasala Kalasala" were also sampled in the song "Don't Sell Out" by rapper Tinie Tempah.[37]

The soundtrack generally received mostly positive reviews from music critics and became a commercially successful album. P.G Devi from Behindwoods gave 3 out of 5 and stated that "Osthi lives up to its huge expectations with generous mass entertainers like 'Kalasala Kalasala', 'Pondatti' and 'Neduvaali'. It will be a top musical grosser, alluring listeners with its hits".[38] Prakash Upadhyaya from Oneindia.in praised Thaman's music sense and claimed that it is Simbu's Diwali treat.[39] Indiaglitz also gave a positive verdict writing that "'Kalasala' the Tamil equivalent of Bollywood chartbuster 'Munni' fulfills all expectations, and even exceeds at some places. If your choice is an album that is a collection of mass numbers, there can't be better pick than Osthi. Go and grab it".[40] Pavithra Srinivasan from Rediff also complimented the soundtrack's "mildly appealing combination of masala beats", giving 2.5 out of 5.[41]

The satellite rights of the film were secured by Sun TV for ₹4.50 crore (US$630,000). The film was given a "U" certificate by the Indian Censor Board. Osthe, was released on 8 December 2011, which coincided with the occasion of Karthikai Deepam.
