Written and produced by Stock Aitken and Waterman, "Shocked" was released as the album's fourth and final single in May 1991 by Mushroom and PWL.

"[8] Hunter Felt from PopMatters enjoyed the song, saying that, while reviewing Ultimate Kylie, that they needed "even a little funk [on tracks like "Shocked"]".

[10] Also Stylus Magazine gave it a positive review, saying that along with "Give Me Just a Little More Time" and "What Do I Have to Do", they "were great songs and suddenly Kylie was a little bit cool.

"[11] In 2020, Alexis Petridis of British daily newspaper The Guardian ranked the song at number five in his "Kylie's 30 greatest singles" list, adding that it saw Stock, Aitken and Waterman "abandoning their identikit sound, writing better, classier songs and... commissioning a remix by DNA which is very 1990 – breakbeat, house piano, rap – and a delight".

Sex came to the forefront for the "What Do I Have to Do" video that preceded it, and Kylie continued in that steamy, seductive vein for "Shocked", with snogging, brassieres and even a spot of keyhole voyeurism no doubt helping her to her 13th successive Top 10 UK single.

Kylie's delivery is flawless and that chorus is perfect".
