To learn Hollywood Undead - Lion chords, your first step should be understanding these chords - Bbm, Ebm, Db, Ebm, Db, B, Gb and Bbm in sequence. I suggest starting at a calm pace of 84 BPM, and as you gain confidence, approach the song's BPM of 169. With Gb Major as the song's key, tweak the capo to cater to your vocal pitch and chord likes.
