"This Is It" is a 1976 disco song written by Van McCoy, and performed by American singer and actress Melba Moore for her fifth album of the same name (1976).

[3] The album's disco-oriented title track was released in March 1976 and became a discothèque favorite: while the "This Is It" single did afford Moore her first major R&B hit, reaching No.

Larry Flick from Billboard wrote, "Vivacious and charming Minogue takes another stab at transferring her European success to the States with an earnest reading of a disco nugget made famous by Melba Moore.

She skips and spins atop a throbbing beat foundation, swerving around a flurry of chirping background vocals, grand piano lines, and fluttering strings.

"[12] Caroline Sullivan from The Guardian said in her review of the Get into You album, "Two seventies covers, Melba Moore's "This Is It" and an authoritative take on the Jacksons' "Show You the Way to Go", are the big moments, all clattering drum machines and Barry White-ish swooning strings.

[15] Alan Jones from Music Week gave the song three out of five, describing it as a "house-inflicted but otherwise faithful remake" and a "typically breezy Minogue single".
