We're Not Happy 'til You're Not Happy is the fifth LP by Orange County ska punk band, Reel Big Fish. The follow-up to the band's moderately successful Cheer Up!, We're Not Happy 'til You're Not Happy' was released on April 5, 2005 on Mojo Records. Compared to the previous album, which was more lighthearted and cheerful, Allmusic describes the songs in the album as "angry" and "embittered", but also deemed the album as "super catchy". Common themes expressed throughout the songs include jealousy, regret, short-lasting fame, and disappointment toward mainstream record companies.
