"If It Takes a Lifetime" is a song by American rock band Cheap Trick, released in 2006 as the third and final single from their fifteenth studio album Rockford.

[2] In a 2006 interview with Star Press, Nielsen told Michelle Kinsey that "If It Takes a Lifetime" was the song he looked forward to playing most during a Cheap Trick concert.

[6] Upon release, Marc Hirsh of The Boston Globe commented of the tracks on Rockford: "...along with "If It Takes a Lifetime," they sound blessedly like classic Cheap Trick songs and performances.

"[7] Alan Sculley of The Desert Sun noted: "The poppier side of Cheap Trick's sound emerges brightly on hook-laden Beatlesque songs such as "If It Takes A Lifetime" and "Every Night And Every Day".

[10] K. L. Poore of Audio Video Revolution noted: "...while listening to "If It Takes a Lifetime" I figure that Rick Nielsen went to his "catchy hook" trunk, pulled out 10 or 15 and crammed them into the same song.
