I mostly just need something to prevent hearing conversations. My brain tunes right into them. My wife used to watch TV to fall asleep to. The slightest conversation going on there can wake me and then, despite how tired I may be, my brain wakes up. Fwiw, she is currently in a no-going-to-sleep-with-the-tv phase. I really appreciate it.
Anything else is too distracting for me.
Asking because I listen to the same kind of music regardless of activity (kpop, if that matters).
