Dead Man Walking - Brent Faiyaz
Real Games - Lucky Daye
Soft Fuzzy Man - Lemon Demon (I especially like the slowed version)
I got a few more but recently I’ve been listening to these to get me in a good mood.
Never - Mag.lo ft. O_super
Borderline - Brandy, and Borderline - Tame Impala (two different songs with the same title)
Doomed - Moses Sumney
For sad songs, They are so good.
