Really, Glee? More Katy Perry? An episode without Sue Sylvester is bad enough, but did we really need yet another Katy Perry Song?

Last year, it was Darren Criss serenading Chris Colfer's with Perry's "Teenage Dream." Sunday, we got a post-Super Bowl version of "California Gurls." On last night's Valentine's Day-themed show, Mr. Schuester gave New Directions an assignment: find "the world's greatest love songs." Who, exactly, on the Glee staff thinks Katy Perry's "Firework," sung by Lea Michele's Rachel Berry, deserves to be on that list?

Just because Glee is a show about high school kids doesn't mean high school kids should pick the music. Has no one there heard of Cole Porter or the Gershwin brothers? Forget "greatest love songs"—Perry's "Firework" isn't a love song at all. It's a motivational anthem, and a super cheesy one at that.

Things started off so well, too, with Puck's desperately inappropriate choice of Queen's "Fat Bottomed Girls." But then we got a soulless version of "P.Y.T. (Pretty Young Thing)" that served mainly to let Mike show off his moonwalking skills, and the Dalton Warblers covering Robin Thicke; aka the Poor Man's Justin Timberlake. The episode finale was especially fluffy: Paul McCartney's "Silly Love Songs." Wouldn't something a little more passionate, like "Maybe I'm Amazed" have been a better choice? The only song in the show that could conceivably qualify for the "world's greatest" list was "My Funny Valentine," the Rodgers and Hart standard. The shame is that we didn't really get to hear it because of Tina's tearful breakdown. Oh well.

Just in case Glee does a Valentine's Day show next year, here's a list of the Ten (Real) All-Time Greatest Love Songs. 10. "I Will Always Love You," by Whitney Houston

9. "Always On My Mind," Elvis Presley

8. "Time After Time," Cyndi Lauper

7. "When a Man Loves a Woman," Percy Sledge

6. "Try a Little Tenderness," Otis Redding

5. "At Last," Etta James

4. "My One and Only Love," Frank Sinatra

3. "Let's Stay Together," Al Green

2. "Unchained Melody," Righteous Brothers

1. "As Time Goes By," Jimmy Durante

Crazy, isn't it? Hard as may be to believe, "I Kissed a Girl" didn't make the list.
