Listen to Usher and Chris Brown's 'All Falls Down'...

'New Flame' collaborators Usher and Chris Brown reunite on an unlucky in love ballad titled 'All Falls Down.'
Over sprinkling piano keys and sparse drums, the pair portray their vulnerable side after getting their hearts broken by a woman. The song is believed to have leaked from Usher's recording sessions for his upcoming new album 'UR.' We all know Usher is a vocalist. However, Chris displayed some real dimension to his vocals here. Nice song.
