[casablanaaaa]

this song is annoying me im trying to find it but cannot remember the song or who sang it!! lol which doesnt help it, all i remember was the video its like a r&b song im in sure it had one of the guys from black eyed peas in it? im not sure though the band had a strange name, in the video there is like this escalator going up into the sky i think? god its annoying me. song came out like 5 years ago. if anyone get this from the little information given i will be shocked and very grateful. i know as soon as i hear who sings it i will remember it straight away. they are not very well known but do have a strange name.
