The album contains songs that have become cornerstones of his legacy. The title track, Imagine, is undoubtedly his most recognized song, conceived as a call for world peace. But it's not the only gem: Jealous Guy, originally an idea called Child of Nature from a 1968 songwriting session, has also resonated deeply. On the other hand, How Do You Sleep? shows a more confrontational facet, written in response to what Lennon perceived as indirect jabs from Paul McCartney on his album Ram. To shape these ideas, Lennon gathered musicians such as George Harrison, Klaus Voormann, Alan White, and Jim Keltner, who contributed their talent to the sessions.
Lennon's experience with primal therapy also left its mark on some compositions. Songs like How? reflect the internal questions that arose during his therapeutic process, while Oh My Love seeks to express the joy and personal growth he was experiencing. The album does not shy away from more energetic rock and roll, as heard in Crippled Inside and It's So Hard, and also includes the political track Gimme Some Truth, which had previously appeared in the sessions for Let It Be. The album's closing track, Oh Yoko!, is an ode to his wife, with a distinctive harmonica touch in the style of Bob Dylan. The album was a commercial and critical success, reaching the top of major charts and demonstrating Lennon's ability to create music that connected on both a personal and global level.
