Nobody expects Greatest Hits albums to do well
Plus, when she performend on Idol she never said it's for her forthcoming album, she always said she doesn't know if it's for a new album or not. She kinda just throw those songs out there.
In addition to that, it's just an album to fullfill her contract with sony. The Cover and backcover are both stills from the Dance Again video and the booklet doesn't even contain new pics. There is zero effort. So, it was expected. Y'all trying too much tbqh.
