There are popular fan-made mashups (often found on YouTube or SoundCloud) that blend Brooks' "Bitch" with Lavigne’s "Girlfriend" or "Sk8er Boi." These are often labeled as covers in file metadata by casual downloaders.

"Bitch," also known as "Bitch (Nothing in Between)," was released in 1997 by Meredith Brooks as the lead single from her album Blurring the Edges The "Cover" Rumors:

Meredith Brooks sang "Bitch" with a knowing, weathered smirk. Avril, at 18, sings it with righteous indignation . In the bridge ("I’m a bitch, I’m a tease..."), Avril’s voice cracks with a youthful vulnerability that Meredith’s version lacks. The M4a codec captures these subtle vocal fluctuations perfectly.
