In the last two years, Katy Perry has transformed from a relatively unknown gospel singer into an international superstar, thanks to her addictive pop sound and undeniable sexual appeal. Her aptly titled new album, “Teenage Dream,” continues with her patented formula of combining not-so-subtle sexual innuendo with the musical and lyrical equivalent of sugar and spice.

Once you gain enough focus to get past the ridiculous cover (Perry essentially lying naked on some cotton candy-esque clouds) and start listening, you’ll immediately notice an album split into two halves; in the first half, Perry showcases upbeat electro-pop, full of Russell Brand influenced lyrics about sex, partying and more sex. Jumpstarting the album are her two smash hits, “Teenage Dream” and “California Gurls,” with “Last Friday Night (T.G.I.F)” sandwiched in between. Essentially the musical version of “The Hangover,” “Last Friday Night” runs down the list of all the things Perry and her drunken entourage accomplished last Friday — including blacking out, streaking and having a casual menage-a-trois.

On “Fireworks,” Perry attempts to steer the lyrics into deeper territory but ultimately ends up with a cliched and somewhat awkward hybrid ballad-dance mix. Luckily, she quickly backpedals to her roots with “Peacock,” a song reminiscent of fellow party-fiend Ke$ha, on which Perry belts out, “I wanna see your peacock,” followed by two emphatic echoes of “cock.” Enough said.

After once again entering dramatic territory with “Circle the Drain,” a tune about her struggle with loving a drug addict, Perry slows down the pace for the rest of the album with ballads like “Not Like the Movies” and “Pace” and some light, fluffy love songs including “The One That Got Away” and “Hummingbird Heartbeat.”

Although I can’t recommend purchasing this album, I know I will probably be out partying to half of the songs on it for the rest of the semester; I guess Ms. Perry gets the last laugh.
