After the monumental success of "Keep on Loving You," REO Speedwagon followed suit with "Take It on the Run," which made it to the number five spot on the charts three months later. This time, the emphasis came from a lonely guitar sound rather than the sweetness of the piano, but the song's love-'em-and-leave-'em lyrical caress and empathetic feel is all the same. Once again, Kevin Cronin's voice gushes out heartache and misfortune with every word, made to sound even larger amongst the song's glistening production. Lush but bright, "Take It on the Run" is beautifully overdone, but it's overdone in all the right places, and REO's full-flavored sound gives the song perfect portions of genuine soft rock charm. REO Speedwagon's bandmembers were already excellent musicians, but Hi Infidelity solidified their songwriting prowess, making it one of the biggest selling albums of the decade. While "Keep on Loving You" was more of an anthem, "Take It on the Run" is personal, even intimate, and Cronin does a splendid job of making the song pertain to him as a character rather than having it sound like a generalized breakup tune. Hi Infidelity led the band into lengthy touring, but REO knew that embarking on a warm, FM-friendly sound saved them from packing it in and calling it quits, and they had to please their fans. Two more songs from the album, "Don't Let Him Go" and "In Your Letter," became Top 30 hits during the summer of 1981. After the ascendancy of Hi Infidelity, REO Speedwagon had a hard time imitating the success of the album, failing to live up to its standards with the disappointing Good Trouble release in 1982.
