Katy Perry is currently enjoying her recent return to the top of the pop agenda, releasing her fourth studio album to rave reviews and eager audience anticipation, and already enjoying tremendous success on the back of her her last two singles. Crammed with the usual dose of bubblegum pop numbers, Prism also features some more mature numbers, and the lyrics on the album are by far some of her most personal to date. Maybe that's why critics are in love with it so much.

Perry is enjoying critical and commercial success with her new album

According to review aggregator MetaCritic, Prism has enjoyed the most positive critical reception of any other KP release, with many of the songs enjoying some credible moments next to the usual presence of throwaway pop numbers that Perry is known for. Some reviews are positively glowing, although others are a little harsher, however there are few that just berate the album content. On the back of this critical success, Prism has managed to score some impressive sales figures already, and has been climbing up album charts across the world.

The personal tone of the album is what makes Prism such a hit with music critics, and whilst her new single 'Unconditionally' may reference her current boyfriend John Mayer, the albums closing track has been the one to catch people by surprise. 'By the Grace of God' recounts the falling apart of her marriage to Russel Brand, in which she recalls crying on the bathroom floor in the poignant, but ultimately positively minded track.

“Well, imagine what you go through,” she told Entertainment Weekly. “Imagine what happens when you go through a break up. We all go through break ups and we all get very depressed and desperate."

Perry, who usually writes with a team of up to six other writers throughout the album, continued to explain her personal writing style further, describing it as "exact and autobiographical." She continued, "The lyrics are very exact and autobiographical. That’s how I write. But the one thing about those lyrics is you can hear me finding my strength throughout the song. It starts off really low and then I kind of stand up for myself and say, ‘No!’”

Prism is out now.
