Hz. and Strong Maurice couldn't have picked a better name to describe the vibe of this single. Comforting guitars coupled with the arrival of lush keys make for a chillhop experience that's pleasantly soothing.
This actually reminds me of that 'classic' sound of chillhop before the genre spread far and wide across the internet. On "Warm Feelings" it's certainly the guitars that hog much of the limelight, and they're brilliantly layered too - to the point where you'll pick up a new arrangement each time you dive into the track.
I can't neglect to mention the drums as you'll find that this is the main reason you can't stop rocking your head back N forth.
