This sounds heavenly
First of all I really dig the drums. They've got this lagging feeling to them, as if they're kind of restrained and it fits my flow here perfectly. I think you're choice of drums here is going to influence how I use drums in my future beats, haha.
The sample, heartbeat, monitor beep, etc all work together devinely. I'm really pumped on this mix man, muchas gracias for putting it up!
