Robert Hilburn of the Los Angeles Times described Rock On as "lively and fun".

[7] Ace Adams of the New York Daily News wrote, "This is the group that had the big hit 'Jack and Jill', and this album shows them at their best.

It has an instant funk sound that will please their fans, plus sparkling vocals and good instrumental interplay.

"[8] The Bay State Banner wrote that, "by settling for imitating everything from rock to Chic, Ray Parker has Raydio floundering around with poor songs, cutesy lyrics and no direction.

"[9] Robert Christgau of The Village Voice gave Rock On a B+ grade, writing, "Ray Parker's idea is to synthesize the old black-music tradition of the male vocal group with the new one of the self-contained funk band, and here he proves that he has what it takes as a composer to keep the idea going.
