As much as she's hated around here, she sells records. Little teen girls don't sit around on OiNK all day complaing about formats and file quality. They buy records. So of course a label is going to go ahead and put another one out.
But don't forget there are a lot of little teen girls who used to really like her, but now really like Fall Out Boy also hate her because she "stole" Pete Wentz from them... don't forget that factor.
