Marina wrote "Oh No!" during a trip to Los Angeles after completing her debut album, driven by a deep-seated fear of failure and the anxiety of not achieving her ambitious goals.

While it didn't reach the top 10, it peaked at number 38 on the UK Singles Chart and has since become a cult favorite among fans, particularly after gaining renewed popularity on TikTok.

Directed by Kinga Burza, the video is heavily influenced by 1990s cartoon aesthetics and Lichtenstein-style pop art. It ironically portrays Marina as a cartoon character surrounded by symbols of wealth and success. MARINA – Oh No! Lyrics - Genius

The lyrics tackle themes of consumerism and the artificiality of media. Lines like "TV taught me how to feel, now real life has no appeal" highlight a sense of disconnection from reality in favor of a curated, successful image.

Produced by Greg Kurstin, the song is an "avant-garde electropop dance-rock" track. It features frantic staccato piano riffs and jittery synths that match the anxious energy of the lyrics.

Marina has described the song as a "part II" to her earlier single "Mowgli's Road." While that track questioned who she wanted to be, "Oh No!" represents the moment she firmly decided on her path toward success, even while acknowledging the neurosis that came with it.

"Oh No!" is a high-energy electropop anthem by Welsh singer-songwriter (now known simply as MARINA), released on August 2, 2010, as the fourth single from her debut album, The Family Jewels .
