A god beat with a sweet surprise towards the end.
I really like the mood this beat sets off at the beginning, emotions of sadness and rage is what i feel from the beginning up to 0:51. Then it's "making the preparations for revenge" from 0:51 to 1:24 and then all hell breaks loose... it is my favorite part. I wish it would have lasted a bit longer, maybe 1 minute longer and have more melodies playing while the drums and rhythm guitar kept on.
I didn't really liked the transition at 0:48, maybe it's just me though but it feels weird. Maybe it's the chord or maybe if the bass drum would link the parts together... i don't know.
Regardless of this tiny factor this is a very solid beat and when i hear it i think of Megaman music because my childhood is a brainwash of video game playing lol :D
Keep up the good work.
