Ever since I subscribed to Spotify Premium I've been an avid playlist creator and subscriber. If you're looking for new playlist suggestions, here are my top recommendations:
Destiny 2: Forsaken - The Cinematic Experience
A playlist inspired by the game Destiny 2. Most of the tracks are electronic and instrumental. Perfect background music while working.
Experimental soundscapes and ambient music, mostly instrumental. Again very suitable as background music when you need to focus. Also, a great playlist if you have tinnitus (like me) and need some background noise.
Something completely different. From 80's training montage music to heavy metal, if you're in need of a high dose of motivation, this is the playlist for you.
