There’s no reason to make life complicated, unless, of course, you’re playing Avril Lavigne’s “Complicated” on repeat in honor of our sk8er girl’s 26th birthday. Yeah, she’s only 26. Who knew? It seems just like yesterday Avril burst onto the scene inspiring girls everywhere to wear men’s ties and heavy eyeliner. (Don’t you remember how many girls in your school dressed up like Avril for Halloween? Let’s bring that back this year! No? Moving on then.)

I’d mostly forgotten about Avril (sad, I know) until the Glee kids sang a version of “Keep Holding Onlast season. After I played that song on repeat for three straight days, I decided to dig deep into my past to see what made Avril so great. And really, her first album Let Go tells the whole story. Avril had a completely different sound than her early 2000 female counterparts (see: Britney or Christina). Along with the aforementioned “Complicated,” “Sk8er Boi“became the anthem for all middle school-aged girls. Rounding out the singles for Let Go were “Losing Grip” and “I’m With You.” (And with that, I think I just found my newest karaoke song.)

I wasn’t much of a fan of her second and third albums. (“Girlfriend,” in my opinion, is one of those grating pop songs that makes you want to stick a fork in your eye.) But she’s reportedly been working on a fourth album. Anyone else wishing for a throwback to the sound that made her famous? What’s your favorite Avril song? And are you, like me, surprised she’s only 26?
