I have a carefully-curated Spotify playlist -- "FLOWSTATE: Repeatable FTW"[1] -- that I specifically optimized for "flowstate" (/Cal Newport "deep work" sessions). The tracks span various moods or vibes, but all are strictly instrumental, w/ limited dynamic range or significant musical variation, and a steady, energizing beat -- ie they're each deliberately repetitive and work well set on repeat. Airpods in, pick a track that resonates w my mood, set it on repeat, set my Pomodoro timer (to remind me to stand and move instead of hyperfocus for hours straight), and I can reliably enter flowstate almost right away.
Wow that was interesting. Every track I listened to had this beat that was way too fast and heavy for me, at least it's not something I could listen to when working - it would send my blood pressure skyrocketing and make me want to go party or something. I guess this sort of thing is highly individual.
Well, it's almost 13h of varied tracks. Most do have a beat but it's much closer to chillout / downtempo than dance music. But yes, ofc, it's highly subjective.
1. Here's the playlist if anyone's interested:
