Seven Year Ache is the third studio album by American country music singer Rosanne Cash, and her second for Columbia Records. It was released on February 27, 1981, and reached number one on the Billboard country album chart. Three singles were released from her album; in the order of the singles' release they were: the title track, "My Baby Thinks He's a Train", and "Blue Moon with Heartache". To promote the album, Cash hit the talk show circuit starting with her appearance on The Merv Griffin Show. The album was mastered a few days following the murder of John Lennon. As a tribute to Lennon, Cash asked the mastering engineer to scratch the message “Goodbye, John” into the run-out groove of the mother vinyl. This etching was limited to the first 25,000 copies of the album.
