 Mustaine has elaborated on the subject matter of several of the album 's other songs as well . He has noted that " Forget to Remember " was intentionally written in an ambiguous way so that it could interpreted as being about either a person trying to forget about a relationship or someone who suffers from Alzheimer 's disease and has memory problems . He also compared the concept behind the song to the film The Notebook . " The Blackest Crow " has a Southern influence and features a slide guitar , while the lyrics are about loss and subsequent depression . Mustaine initially hoped to have a guest feature on the song , and reached out to country musicians Willie Nelson and Miranda Lambert ; however , neither appeared on the song . " Don 't Turn Your Back ... " was inspired by a friend of Mustaine , who described him as " the kind of guy that will steal your dope and then help you look for it . "
