I want a dark and aggressive rap beat, around 140 BPM. The overall vibe should be tense and gritty. Use heavy 808 bass and punchy kicks to add power. Include dark synths and ambient effects in the background. The verses should be more minimal and low-energy, but the chorus should hit hard with a sudden rise in intensity. Add dramatic strings or choir vocals during the hook to really pull listeners in. The beat should be hype and energetic, but also carry a threatening, street-style atmosphere.
