Katy Perry’s much anticipated sophomore album, “Teenage Dream,” leaves no room for disappointment. Perry has the ability to please the crowd with her ever-popular upbeat tracks, while simultaneously showing off her strong vocals and singing of self-discovery and love.

“Teenage Dream” debuted at number one on the Billboard Top 200 during the week of September 18. Two of the pre-released singles, “California Girls” and “Teenage Dream,” were instant hits with listeners. The former has held a spot in the top 10 of the Hot 100 for 17 weeks now. The title track is currently number one on the Billboard Hot 100.

Perry has had time to grow into her role as one of the popular, more in-demand, pop stars of today. She has evolved as an artist since the release of her debut album, “One of the Boys,” in 2008. Perry’s growing maturity as an artist is present throughout the new album; she sings about a love lost (“The One That Got Away”), confidence (“Firework”), or discovering her own identity (“Who Am I Living For”).

Perry also experiments with different beats and styles on various tracks. “Circle the Drain” has a harder rock undertone to complement the anger and frustration she is singing about. Likewise, the tracks “E.T.” and “Who Am I Living For?” have a heavier, eerie style to them.

Although many of the singles Katy is famous for do little to show-off her vocal abilities, “Pearl,” “Firework” and “Not Like the Movies” perfectly exhibit her range as an artist. Her vocals are strong on all three tracks, but they also display her ability to sing about more than crazy parties, the ideal “California Girls” and dreamy summer flings.

The fun, catchy dance-floor anthems are still the highlight of the album. “Last Friday Night,” “Peacock” and “Hummingbird Heartbeat” are the three tracks––aside from the two hit singles––that demonstrate that Katy Perry hasn’t strayed too far from the upbeat party tracks that first made her famous: “I Kissed A Girl” and “Hot N Cold.”

Because of the varied styles of the tracks, the album is not perfectly cohesive, but Perry’s super-stardom and ability to make an enjoyable range of different tracks make this album a success.
