This is a blatant publicity stunt, everyone is talking about this mediocre song just because it's Avril Lavigne. Lavigne and Kroger aren't stupid, they know most people hate their music, so by getting the haters to talk about it everyone else starts watching it, and then some people think 'its not that bad' and buy it, easy and cheap publicity that's very effective.
Also Avril is more popular in Asia than the US I believe so it makes sense that she'd play to that market where she is still loved.
