In an interview with Archana Chandhok on Zee Tamil, Rajinikanth revealed that director Shankar wanted to make 2.0 without any songs.

[1] The track "Enthira Logathu Sundariye" made its way after taking into account that the screenplay of the film was entirely subject-oriented and moves at a frenetic pace.

Madhan Karky's lyrics in the duet Endhira Logathu Sundariye speak of a romance between a male and a female robot.

Raajali is an anthem-like number that celebrates the triumph of good over evil, a typical sentiment in Rajinikanth movies.

Free from the mandate of having to be a theatre-shattering Rajinikanth song, the melodious Pullinangal's arrangement and mixing is low-key with strings, a simple synthetic beat, some piano and recordings of bird sounds.

Though it is a love song that is ultimately not for a person, the singers (AR Ameen and Suzanne D’Mello sing all three versions, accompanied by Bamba Bakya in Tamil, Kailash Kher in Hindi, and fellow composer MM Keeravani in Telugu) sing their heart out, bringing an emotional weight missing from the other two tracks.

[5][6] A promotional music event for the film was held at Burj Al Arab, Dubai on 27 October 2017, with Rajinikanth, Akshay Kumar, Amy Jackson, composer A. R. Rahman, director Shankar, producer Subaskaran and the film's entire technical crew, along with Dhanush, Aishwarya R. Dhanush, Kamal Hassan and other celebrities attended the event.

[14] Srinivasa Ramanujam, from The Hindu, reviewed the soundtrack album, stating that "The focus of Rahman's work in these two released songs for the Shankar-Rajinikanth film clearly seems to be on providing a futuristic soundscape rather than concentrating on tune – perhaps aligning with the sci-fi elements in the script.

"[15] M Suganth, from The Times of India, reviewed the album, summarising it "As with Endhiran, Rahman has come up with songs that are global in sounding, but still distinctly local with 2.0.

The singer is a breath of fresh air in this album which otherwise has nothing we have not already heard of, and also reviewing "Raajali" as "the track that uplifts the soul of the movie.

The singer who otherwise was known for his addictive melodies like "Yennai Matrum Kadhale" and the latest hit "Maruvaarthai" has proved that he can be the voice behind such peppy and high techno songs too".

[1] Unlike previous projects, Rahman began finalising the original background score six months back prior to release because he felt that the scenes were very heavy and it needed a lot of work.
