This mid-tempo tune is the first single to be released by Green Day from their trilogy of albums titled ¡Uno!, ¡Dos! and ¡Tré!. "The first one is power pop," frontman Billie Joe Armstrong explained to Rolling Stone of their three long players. "The second is more garage-y, Nuggets-type rock. And the third is supposed to be epic. With the first album you're getting in the mood to party. On the second one, you're at the party. And the third album you're cleaning up the mess."
The song was recorded in Jingletown Studios, Oakland, California and released digitally July 16, 2012, the same date that it impacted radio. It is the final track on ¡Uno!. "What I really wanted to do was write real power-pop kind of music that had that old Green Day energy," explained Armstrong to Billboard magazine, "so the original Green Day sound became '¡Uno!'"
The song deals with matters of the heart and sexual tension. "'Oh Love' is kind of like leading with your heart and not necessarily with your brain as much," Armstrong told MTV News. "And [also] kind of maybe losing your mind, and shooting a little bit more from the crotch area."
