Katy's third album is a great success for me

Just off the front, I also have the two previous albums (One of the Boys, Teenage dream) of her and found this really great.
The new album by Katy has a lot of variety, some innovations such. As more of the "hip-hop" style like the song "Dark Horse". Even with the title single (and also good earworm) "Roar" new facets as jungle like sounds can be recognized, but it fits so well to the title of "Prism" at least as regards the mentioned many facets :)
All in all I think it's something new and yet Katy remain faithful to their style, so that they also recognize and that's good!
For all Katy fans definitely recommended, it has made good, keep it up :)
