Damn, Moth into Flame is really good. Was really not expecting that. Death Magnetic was a big disappointment. It had a lot of potential, but wasn't produced well at all, sonically and in terms of song structure and pacing. The songs were bloated with unnecessary and awkward transitions.
Hardwired was a fun song, but a little cliché and lacking some musical depth. Moth into Flame has me really excited. The structure is well thought out, the song has a right balance of melody. The lyrics have substance to them. Sonically, it sounds great.
I really didn't think they had it in them. The only draw back is Kirk's solo. He seems to have forgotten that what made him successful was his ability to couple speed with melodic leads. Now he just wails the pentatonic scale almost at random with no regard to actually creating a melody.
