The "power pop" of "My Sharona", coupled with the band's "retro" 1960s look, earned the band comparisons to the early Beatles. Many music critics of the era disliked disco, which dominated the music industry at the time, and were, at best, coolly receptive to other developing genres like punk rock, new wave and heavy metal music. The Knack's power pop and hard rock influences earned them some critical credibility. After subsequent albums, there was a critical backlash against the band and they broke up amidst internal squabbles. They have re-united periodically over the years and are currently still active.
