Including the various bonuses floating about, Guilty Pleasure is twenty tracks of pure pop-rock at its finest that you really shouldn’t feel guilty for enjoying. Songs like the wonderfully-named Hot Mess, Masquerade, Delete You and the eponymous Guilty Pleasure will lodge themselves in your brain within a couple of listens and need Herculean levels of persuasion to coax them out again. Tisdale channels a Britney-Blackout lite on Crank It Up and Blame It On The Beat to winning effect; Acting Out, Overrated and Tell Me Lies are in the vein of Avril or Ashlee before they got too annoying whilst Erase & Rewind manages to be reminiscent of Katy Perry yet better than the majority of her album, without a whiff of Sapphic scandal in sight. Hair and Switch are cheesier than a platter of mouldering Roquefort yet substantially more delicious. Meanwhile, the Disney schmaltz that smattered her debut album is thankfully kept to a minimum – quality control ensures that even this balladry (the lush Me Without You and What If) is actually quite nice.

Tisdale might not have the vocal strength of a Clarkson, or even a Perry, yet she does have a distinctive tone that brims with character and charisma, rather like Tisdale herself (her Sharpay remains the mischievous knowing glee that anchors HSM). Guilty Pleasure will not change the world yet is all the better for knowing its boundaries. As a result, it’s frivolous fun that has not left my music player since its release.

And though the 23-year-old actress and singer wasn’t even born when Thriller came out, she told MTV News that Jackson was a big influence on her music and the work of her “HSM” castmates.

“I’ve loved Michael Jackson, his music, his music videos,” Tisdale said. “I mean, the man made music videos what they are today. So, I’ve always been inspired by him. I think he’s such a great dancer.

“It was definitely a shock,” she added of Jackson’s sudden passing. “It’s really hard when a celebrity dies out of nowhere, ’cause it’s very shocking … surreal.”

Tisdale was looking forward to seeing what Ortega and Jackson would be debuting on July 13, when Jackson was scheduled to kick off his This Is It tour. She said she and her “HSM” buddies were going to make the trek overseas to see it for themselves.

“We were all gonna go see him in London and go visit and watch the show,” she said, adding that the show would have also included dancers from the “HSM” movies. “We had a lot of our dancers in the production as well. I know they’re going through as really hard time as well. Hopefully, he’s in a better place now.”
