I'm not sure if anyone has done this before but I randomly thought of this. Basically, person A puts their favorite ost (can be from any country) and person B listens to it and either puts "like", "dislike", "meh", then person b puts their favorite ost. It's your choice to put the drama in parathesis or not. Of course, I am not forcing you to listen to it, it's your choice. I thought it'd be nice! Also, I kinda got the "like-dislike " idea from THIS forum game made by @Sunset.

person A:

person B:
