When someone first brought this to my attention, I thought it was a joke. It’s not.
Avril Lavigne (Queen of the posers) has covered a song by System Of A Down (Kings of modern metal). Yes, it’s as bad as it sounds.
I don’t want to scare people but here is the link Avril Lavigne – Chop Suey (Cover). I don’t know how long that link will stay up, so don’t hassle me if it stops working. Please exercise caution before listening – it will hurt.
