"I Don't Wanna Know" is a song by American R&B artist Mario Winans featuring rapper P. Diddy and Irish singer Enya. The song is based on a sample of the Fugees' song "Ready or Not", which in turn samples the synthesizer riff from Enya's song "Boadicea".^[1] The drums are sampled from the end of EPMD's "You're a Customer".^[2]

Released on February 17, 2004, "I Don't Wanna Know" spent eight consecutive weeks at number two on the US Billboard Hot 100, behind the Usher singles "Yeah!" and "Burn", respectively,^[3] and reached number one in Germany, the Netherlands, and the United Kingdom. It became a top-10 hit in many other countries, including Australia, Canada, France, Ireland, and New Zealand, and has received multiple sales certifications.

In 2022, record producer Metro Boomin, singer The Weeknd, and rapper 21 Savage released the single "Creepin'"; a cover of the song mainly performed by The Weeknd, except with a new rap verse from 21 Savage instead of P. Diddy. Winans himself contributed to this version, while Diddy himself would be featured on the official remix of the song, released in March 2023.^[4][5]

The song is sung over a background track that samples "Boadicea" by Enya from her 1987 album Enya, inspired by the use of the sample in the Fugees' 1996 hit single "Ready or Not".^[6] Winans said: "I first heard 'Boadicea' at the end of the movie Sleepwalkers about five or six years ago. It's something I always wanted to produce. Then when The Fugees did it, oh my God, I loved it."^[7][8]

Vibe wrote that "Winans adds a simple stuttering beat that prevents the song from devolving into murky, saccharine Muzak. This is the secret of Winan's magic; the soft touch of the synthesizers and his gentle piano playing blend with the signature sound of the kick and snare – hard, unadorned, punching through the music's gauzy elegiac texture."^[9]
