"I'll Never Stop" is the third single from 'N Sync's third European studio album, No Strings Attached. The song peaked at #13 in the UK, at #23 in Germany and at #28 on the Dutch Singles Chart. The music video features four fans listening to No Strings Attached, dancing around to various tracks and beats. The video also shows clips of *NSYNC at different events. The girls are also seen watching *NSYNC on TV.
The single (and song in general) was only released in Europe. The radio edit would be released worldwide to promote 2005's Greatest Hits.
Mysteriously, it was the biggest-selling cassette single in the UK in the years 2009, 2010 and 2011 long after the cassette medium was rendered obsolete by other music formats. It sold 24 copies in 2009, 13 copies in 2010 and 11 copies in 2011. It is likely that a sole retailer in an unknown part of the country had copies continuously on sale.
