I never use non-private windows, so I use Invidious or mpv for this. I put

  control + alt + m
    notify-send "mpv loading $(xclip -o)"; mpv --player-operation-mode=pseudo-gui "$(xclip -o)" || notify-send 'mpv error'

in my ~/.config/sxhd/sxhkdrc to conveniently play any youtube-dl supported url I’ve copied or highlighted.
