"Gotta Tell You" is the debut single by Irish singer Samantha Mumba, released in 2000. The song was written and produced by the Swedish team BAG & Arnthor (Anders Bagge and Arnthor Birgisson). It was an international hit, peaking at number four on the US Billboard Hot 100, where it spent 21 weeks on that chart, number one in Ireland and New Zealand, number three in Australia and number two in the UK. The song is Mumba's biggest hit, as well as her signature song. This was also featured on the 2001 compilation album Now That's What I Call Music! 6.
The music video shows Mumba walking, running and dancing around a city and running to catch a plane. It also includes Mumba doing minor stunts which include flipping off a building onto the street and jumping onto and off a moving firetruck. The video was shot in city of Fuengirola, Málaga, Spain.
Irish DJ Micky Modelle remixed the song in 2008. After Mumba heard the remix, she liked the song and re-recorded some of the vocals. She promoted the song on the Clubland Live Tour in 2008 and it was released on 25 August 2008 through All Around the World Productions. This is the final single to be released from Mumba following her announcement of retiring from music in 2011.
A video for the song was filmed throughout London and Belfast in May 2008 and was premiered on 13 June 2008. The video features Micky and Mumba in a conference room with various clones of Mumba as various maps of cities in the UK moving around her, with the maps indicating that "Club energy levels are low".
Mumba and the clones of herself go out to the cities clubs where the people in the club start dancing and the club energy levels are restored.
