what is this italian advert song?

[flavzi]

i heard a song on an italian advert about 2 months ago which unfortunately they have stopped airing on the television. the lyrics are in spanish but i only managed to catch a few; '....otra vez......tu corazon, cada noche, cada dia, cada ora tu eres mia, por bailar, por bailar, por cantar'  i've looked everywhere for this song title and the band but i haven't been able to find it. could you reccomend a site to look on or perhaps, if you know, tell me what song this is?!
