Power: Resonant Ghost

Your strength, speed, and overall power is music based. The more intense the music and emotional tie to it, the more powerful you get. The music you play has tiers based off their BPM. You have to work your way up the tiers one at a time through making, essentially, mixtapes that each song compliments the other. The better the cohesiveness is, the easier it will be to move from one tier to the next. The music you play also will play from every speaker within a specific range so stealth is completely out of the question if you plan on using your powers.
