The song is called "Guys Like You Make Us Look Bad"
Since losing Craig Mabbit mid-tour (for "personal reasons"), Blessthefall's bassist was left to cover for him while playing the bass for the remainder of the tour. Later on when Craig showed interest in rejoining the group, they decided to move on and picked up Beau Bokan, former Take The Crown front man. Take The Crown had previously disbanded, so this is probably a big break for him. The next video features Bokan with Blessthefall as they currently are.
My next post will probably include The Word Alive, as they've made a big change after losing Craig Mabbit as well.
