[2] The song was subsequently re-recorded by several artists, including Paoli himself, Franco Simone, Ornella Vanoni, Giorgia, Carla Bruni and Mike Patton.

Since Paoli was not registered to the Italian Society of Authors and Publishers, "Il cielo in una stanza" was initially credited to Toang and Mogol.

[4] Paoli explained that the song was inspired by the one-night relationship with a prostitute: "I wanted to describe the moment in which you are in a bed with a woman, you just had sex, and in the air you feel a sort of magic, which you don't know where it comes from and which immediately vanishes.

[5] The song was initially proposed to other Italian singers, including Jula De Palma and Miranda Martino, but they turned down the opportunity to record it.

[7] In 2010, the linguist Giuseppe Antonelli considered the lyrics of the song as very modern, praising Paoli for his "artistic sensibility" and for the decision to adopt a language which is very close to spoken Italian.

[8] Gino Castaldo of the Italian newspaper la Repubblica also applauded Mina's performance, claiming in 1988 that the song marked a change in her vocal style, who became a mature interpreter with "Il cielo in una stanza", discovering she could "give voice to an important song, making it higher, unaccessible" and departing from the urlatrice style which characterized her previous production.

[11] It then appears in the 1961 film Girl with a Suitcase, directed by Valerio Zurlini, during a scene in which Romolo, performed by Riccardo Garrone, tries to kiss Aida (Claudia Cardinale).

[13] Dolce & Gabbana brought in Scorsese to direct its 2013 advertisement featuring Scarlett Johansson and Matthew McCanaughey, as a commercial for its perfume "The One.

In 1969, she included a new recording of "Il cielo in una stanza" on I discorsi, released under her own label PDU, while 1988 album Oggi ti amo di più features a new version performed with pianist Renato Sellani.

[23] In 1971, Paoli included a new version of the song, arranged by Giampiero Boneschi and produced by Alberto Martinelli, in his album Rileggendo vecchie lettere d'amore, released by Durium Records.

[26] In 1976, Italian singer Franco Simone included his own version of the song in the album Il poeta con la chitarra.

[31][32] Bruni later re-recorded the song as a duet with Gino Paoli, which was featured in his compilation album Senza fine, released in 2009 to celebrate his 50th year of career.
