Today while shopping there was this song from Rihanna playing. She and some rapper (I think he sounded like Sean Paul) were singing alternately. It sounded like a pop-rap mix.
There was this line in the refrain being something like "(Rihanna) :"Let there be no other" (male rap voice): "let there be no one". A characteristic thing was, that Rihanna's "other" was going through a few musical notes. (I think this is how you say it, I'm no musician.)
Does anyone know what song this could be?
