When "Last Friday Night (T.G.I.F.)" went No. 1 last month, Katy Perry became the first female artist - and only the second overall after Michael Jackson - to unleash five No. 1 singles from the same album.

When "Last Friday Night (T.G.I.F.)" went No. 1 last month, Katy Perry became the first female artist - and only the second overall after Michael Jackson - to unleash five No. 1 singles from the same album.

Circa "I Kissed a Girl," this would have seemed ridiculous and stupid. But the disc in question, "Teenage Dream," is as perfect as pop albums come.

Sure, it's vapid and shallow, not as political as Lady Gaga or outright sleazy as Ke$ha. But it's exactly the sort of adolescent fairy-tale music it's intended to be, with relentless melodies riding club beats that pump harder than hormones.

Plus Perry's ridiculously elaborate videos are a trip. She's a deserving queen of pop.
