Feelin' Satisfied

Paul Grein of Billboard described the song as "an affectionate tribute to the power of music."[4] The same magazine later described the song as an "upbeat track which is totally rock 'n' roll," praising the "clear singing" and "fresh sounds."[5] Cash Box said it has "those Boston characteristics that has made the group a platinum act: tight-skin percussion, majestic guitar lines and do-the-job soaring vocals."[6] Cash Box also called it a "fine track."[7] Record World called it "one of [Don't Look Back's] most powerful rockers" and praised the guitar playing, Brad Delp's lead vocal and the "multi -track vocal hook."[8]

Terry Hazlett of The Observer-Reporter described the song as an "innocent little [ditty]" which comes across like a "rock 'n' roll anthem."[9] Pete Bishop of The Pittsburgh Press claimed that it has "an infectious happy feel."[10] But Press & Sun-Bulletin critic Chris Carson described "Feelin' Satisfied" as being "on par with the filler" on Boston's debut album.[11]

AXS contributor Bill Craig described the lyrics as being about "the wonders of rock music."[12] Ultimate Classic Rock critic Michael Gallucci described it as a "simple" song that, in common with many Boston songs, "celebrates rock 'n' roll."[13] Gallucci rated it Boston's 8th greatest song, particularly praising the effect from the hand claps during the refrain.[13] Paul Elliott rated it their 7th greatest song, commenting on its "sense of fun" as Scholz lets go of some of his usual control.[14] Elliott described it as a "grooving hard rocker."[15] Classic Rock History critic Brian Kachejian rated it as Boston's 8th best song.[16]
