The best indicator of whether this will matter to you is whether you know Avril Lavigne is about more than just the track involving the skater boy. If you're aware that since her first big hit she's released three more albums, each one a yardstick for her evolution from tomboy to rebel rocker to wised-up woman, please carry on.
Making her debut in 2002 as the one-of-the-guys alternative to her overtly sexual pop contemporaries, Lavigne also stood out from the crowd by writing her own material. Her latest album, Goodbye Lullaby, comprises songs she either wrote or co-wrote. It's a more stripped down, mid-tempo effort than you'd expect from the scrappy teen who made her name with pop-punk hit singles such as 2002's Complicated and the evocatively spelled Sk8er Boi.
Like so many pop stars, her name alone can launch, if not ships, then perfumes, so Lavigne is also a designer, actress and philanthropist. Last year, she worked with Disney to design Alice in Wonderland-inspired clothes for her fashion line - this subsequently led to her writing the song Alice for the soundtrack to the Tim Burton film.
