Compared to its multi-platinum status in Europe, O-Zone never entered the charts in the United States. With the advent of the Numa Numa Dance, "Dragostea Din Tei" had a boom of popularity in the United States, but was rarely played on the radio.

In 2005, the group split up. All of the members went their separate ways and started their own solo careers. Arsenie Todiraş was a co-representative of Moldova during the 2006 Eurovision contest, competing under his new moniker Arsenium.

        Los Angeles resident Dan Bălan was born in Chişinău, Republic of Moldova, 06.02.1979. His biggest success to date was with the pop band O-Zone. He was the front man of this project, producing and writing all of their compositions. Dan formed O-Zone in 1999 and released three albums through 2004. Their best-selling LP was DiscO-Zone, which reached #1 in six countries and sold over 2.5 million copies worldwide (1,000,000 in Japan alone).

Dan’s most successful song to date is "Dragostea din tei". The song reached #1 in 32 countries (and #3 in the U.K.), selling 12 million copies worldwide. It was the biggest single in Europe and Japan in 2004 and 2005, respectively. The song was eventually covered by over 100 artists worldwide in 12 different languages.

The "Numa Numa" video clip was a Newgrounds classic released in 2004.

The song was featured in a famous viral video on the Internet by Gary Brolsma. In this video, Gary lip syncs and dances to the pop tune. The video can be found throughout the Internet, and many spoofs and remakes have also been made.
