Mario Mendell Winans (born Mario Mendell Brown) is an American singer, record producer, songwriter, and multi-instrumentalist best known for his 2004 song "I Don't Wanna Know", which reached number 2 in the United States and number 1 in the United Kingdom. Winans also won a Grammy Award for Best Gospel Performance for co-writing CeCe Winans's song "Pray".
Winans recorded his second album Hurt No More in 2001, 2002, and 2003 in between working with other artists. The album is based on stories of love and betrayal.
The first single "I Don't Wanna Know" was based on a sample of the Fugees' 1996 hit single "Ready or Not", which itself was based on a slowed-down sample of the instrumental track "Boadicea" by Enya from her 1987 self-titled album. Enya and her representatives became angry when Winans did not seek her approval for the sample, as he was unaware that the Fugees sample he had used had itself been a sample. So, a compromise was reached to credit the single as "Mario Winans featuring P. Diddy and Enya". The song features a rap by P. Diddy. The song was released as the single in early 2004 and became a worldwide hit, reaching number 1 in Germany and the United Kingdom and on the rhythmic top 40 radio chart in the United States; to number 2 on the Billboard Hot 100 and the US R&B/Hip-Hop singles chart; and to number 3 on both the Australian and Norwegian singles charts. It also reached the top ten on a composite European singles chart.
