5. “Teenage Dream”
The title track from Perry’s 2010 sophomore effort was incredibly electrifying. One of numerous number one hits from Perry, it’s nothing short of addictive and sorta tastefully naughty. Balanced, “Teenage Dream” appealed to broad bases. “You make me feel like I’m living a / Teenage dream the way you turn me on / I can’t sleep / let’s runaway and don’t ever look back, don’t ever look back…” Sigh… and we haven’t Katy, we haven’t.
