Prism (album)

***Prism*** is the fourth studio album by American pop singer-songwriter Katy Perry. It was going to be much darker than her earlier material, though it became an upbeat, dance-inspired album. The songs "Roar" and "Birthday" are on the album.  The album debuted at number one on the US _Billboard_ 200 with first-week sales of 286,000 copies.  _Prism_ features the singles "Roar", "Unconditionally", "Dark Horse" featuring American rapper Juicy J, "Birthday", and "This Is How We Do".  The first and third singles both reached number one on the _Billboard_ Hot 100, while the second and fourth singles became top-twenty hits in the US.
