AllMusic critic Matthew Greenwald regard "¡Que Vida!" as a "true groundbreaking composition for Arthur Lee" in the way the allows the song to flow freely in the direction it wants to go. Greenwald also notes that although the chordsalwaysresolve, they go in surprising directions. Edna Gundersen and Ken Burns of USA Today described the song as "summery jazz-pop". Sean Elder of Salon calls the song "whimsical" and notes that it "almost seems like a parody of a hippie song, punctuated with what sounds like a pop gun."
