Odd question. Close down winamp without closing it down?

[Makta]

I recently formated my PC after way to many years without doing so and i went over to windows 10 from win 7! And i could have sworn when i hit the x on windows 7 winamp would close down to the system tray whitch i have figure out now aswell BUT it would not stop playing music/respond to my music keys on my keyboard?

Tried to google around like i probably did all those years ago but i found nothing and i am 99% sure i was mostly x'ing down winamp and not minimizing.

Is there any way to set this up? I know i could just minimize it and it works but it feels so off now for some reason.

Cheers.
