"The Music's No Good Without You" was released as the album's worldwide lead single, and made Cher one of the few artists to have a top 10 hit in the United Kingdom in five consecutive decades.

On March 9, 2024, it was announced by Dion Singer via Instagram that Living Proof would be released on vinyl for the first time on June 28, 2024.

[5] Cher said her favorite song slated for the album was a cover version of "When the Money's Gone", written by Bruce Roberts, stating it was "so perfect" for her.

The Dallas Morning News commented that "even with a pensive look on her exquisitely snipped and tucked face, she commands attention".

[8] The international version for Living Proof opens with "The Music's No Good Without You", a disco-inspired song filled with "hypnotic synth lines",[9] while Cher's vocals are manipulated with Auto-Tune which made her sound like the "embodiment of a haunted extra-terrestrial".

[10][11] The following track "Alive Again" is described as a "trance anthem",[12] and its lyrics revolve around Cher singing about the "broken world of a dissolved relationship".

[12] The following track, "A Different Kind of Love Song" lyrically alludes to themes of tragedy, heroism and brotherhood,[15] while musically it has "cloud-scrapping chorus, breezy melody, and a kitschy production tics", including Cher's heavily processed vocals by Auto-Tune.

[12][1] The eighth song "Love Is a Lonely Place Without You" lyrically carries the theme of a "brokenhearted symbol of a strong but decidedly single woman".

[12] The closing song, a cover of Bruce Roberts' "When the Money's Gone", is an "airy track" which has "rapid-fire drum beats".

[1] To start marketing Living Proof, Cher made an appearance on German TV show Wetten, dass..?

She opened the 2002 American Music Awards on January 9, 2002 singing "Song for the Lonely", accompanied by dancers and wearing a blonde wig.

[32] Cher also sang "A Different Kind of Love Song" on the comedy series Will & Grace in 2002, where she made a special guest appearance in the episode, "AI: Artificial Insemination Part 2", as God.

[43] It was a success in the United Kingdom, reaching number eight on the UK Singles Chart, while Cher achieved the feat of having a top 10 hit in five consecutive decades there.

[59] Baby A. Gil, writer for The Philippine Star, praised the album as "another rousing dancefest", while noting that Cher's singing was "in full control and in better form than it was during her early days", calling it an "excellent example" that time can stand still.

[60] Sal Cinquemani from Slant Magazine was mostly positive, noting that "each track pumps with melodies so thickly contagious that their hit potentials are essentially guaranteed", while even the album's weakest moments maintain the high-energy, club-ready pace.

[56] Colm O'Hare from Irish magazine Hot Press exalted the album's international lead single "The Music's No Good Without You", noting it uses the same voice effect from "Believe", and said "it's almost a 'Believe' Part Two proving that nothing succeeds like repetition".

[61] Barry Walters from Rolling Stone gave a mixed review, saying that Living Proof "endeavors to make lightning strike twice in the same place.

[...] Unlike house music or modern R&B, Cher's twenty-first-century disco is built on fully fleshed songs and detailed arrangements, and the studio wizardry is even grander than before", but also felt that it "lacks its predecessor's unexpected impact".

[15] AllMusic's Kerry L. Smith called it a "peppy dance album that spouts warm sentiments and reverberating sounds to keep you going all night long", however noted that the power of the album's punch loses its luster when the Auto-Tune transforms Cher's "deep, sexy voice" into a "canned electronic robot dialect".

[55] The Dallas Morning News gave the album a C grade, saying Living Proof set itself up for failure by "shamelessly" copying and then overdoing the formula that made its predecessor artistically and commercially contagious.

After spending 11 weeks on the chart, the album was certified Gold by the Bundesverband Musikindustrie (BVMI), for shipments of 150,000 units.

[70] In the United States, Living Proof debuted at number nine on the Billboard 200 albums chart, with first-week sales of 82,000 copies on the issue dated March 16, 2002.
