music video

[ohho78]

hi can anyone tell me the name of a song.... i saw the video today on this channel called MCM it was number 15 in the top 50 charts but the website's chart isnt the same as the one i saw on tv. the video is of a young woman walking through a town at night (i think amsterdam) and singing with the music while wearing some headphones. in the video there are also 3 dancers (2 male, 1 female) and they morph into stick figures which look like the 'don't walk' and 'walk' signs that light up when you cross a busy road. the lyrics go 'hey hey hey' and then i cant understand the rest...the song is sort of dance/house and there is a club scene too. please please can anyone give me a clue because its stuck in my head and i really like it!! thanks
