My column for Friday’s GO was inspired by Avrilgate – you know, recent accusations that Avril Lavigne ripped off the Rubinoos and Tony "Mickey, you're so fine" Basil for her single “Girlfriend.”

In the column, I also mention a few other songs I've heard in recent years that inspire a sense of deja vu. None of us (presumably) were there when the songs below were written. So I'll let you be the judge regarding whether they're intentional ripoffs, examples of the artists' influences being just a little too transparent or just -- um -- total coincidence. There are only so many notes that you can play, right?

For starters, Avril Lavigne’s “Girlfriend” sounds kind of like a mashup of ...

... The Rubinoos “I Wanna Be Your Boyfriend” and Toni Basil’s “Mickey.”

And maybe you also noticed that Fergie's corny club hit “Fergalicious” is eerily reminiscent of ...

... JJ Fad’s “Supersonic.”

If you picked up Link Park's new album "Minutes to Midnight," snippets of “Given Up” ...

... may have reminded you of Ministry’s “N.W.O.”

I love Lily Allen’s “Knock ‘Em Out.” But it wasn't until I heard a clip of ...

... Professor Longhair's “Big Chief” on a TV commercial that Lily's source material became evident.

Last year's "Girlfriend" was the Red Hot Chili Peppers’ “Dani California,” which -- as many a writer pointed out -- sounds a lot like ...

... “Mary Jane’s Last Dance” by Tom Petty.

Not that Petty gets off the hook himself, since “Saving Grace,” a track from his most recent album, is a dead ringer for ...

... ZZ Top’s “La Grange.”

Meanwhile, the riff from Jet’s “Are You Gonna Be My Girl” recalls ...

... a sped up version of Iggy Pop's “Lust for Life.”

And when My Chemical Romance was writing their concept album "The Black Parade," which includes the track “The End” ...

... I wonder if they used “In the Flesh,” Pink Floyd's intro from "The Wall," as a template.

And last but not least, there's the one that Pearl Jam haters are quick to point to. I happen to like those guys. But you've gotta admit that the vocal melody from “Given to Fly” ...

... is a lot like Robert Plant's singing on Led Zeppelin's "Going to California."
