Musically, the album represents a departure from her 2007 effort “Good Girl Gone Bad”, which contained up-tempo and ballad-oriented songs. Conceived after Rihanna's assault by her then-boyfriend, singer Chris Brown, “Rated R” features a foreboding and atmospheric tone in terms of musical and lyrical direction. It incorporated elements of hip hop, rock, and dubstep. It also explores other genres, such as dancehall in "Rude Boy" and Latin in "Te Amo". In the United States, the album debuted at number four on the Billboard 200 chart and sold 181,000 copies in its first week. It also attained top ten positions in over twelve other countries.
