"Can't Fight This Feeling" is a power ballad[4] performed by the American rock band REO Speedwagon, written by lead singer Kevin Cronin.

"[11] The other REO Speedwagon members referred to "Can't Fight This Feeling" as "that stupid ballad" until it became a charting hit.

"[15] DeKnock also said that it was "the latest in a series of ballads that have found success on the dance-dominated charts with a tried and true formula: A melody that is pretty enough for adult contemporary listeners, with instrumentation that is strong enough for rock-oriented radio stations.

[19] Arizona Republic writer Andrew Means noted that the song "has a similar tone of emotional frailty [as some ballads on Hi Infidelity], which revives comparisons with such so-called 'corporate rock' entities as Foreigner and Journey.

"[21] Austin American-Statesman writer Drew Carr felt that the performance of REO Speedwagon keyboardist Neal Doughty was particularly effective on this song.

After Cronin exchanges some laughs with his bandmates, the original track of the song plays, with the band members miming their respective parts.

"[23] The second more famous version, directed by John Jopson, was considered a "more professional one" and makes various references to the life-cycle and shows the band singing the song.

In 2019, English indie pop band Bastille released a cover version of the song, featuring the London Contemporary Orchestra.
