I used to keep one list per group. It looked tidy and I never listened to any of it. Sorting by mood fixed that.
06:30Morning
Bright and fast, nothing with a long intro.
10:00Focus
Instrumental versions and b-sides you already know by heart.
18:00Gym
Anything with a dance break. Bonus points for a key change.
23:00Late
Ballads and slow R&B. Lights off, phone down, ideally.
The one rule
If I skip a song three times, it moves out. Short lists get played, long lists get scrolled.
B-sides first
Title tracks find you on their own. The album cuts are where you find out what a group really sounds like, so give every new album one full listen in order before you pick favourites.
