For me it wasn't like I listened to this one song, and all of a sudden I became addicted. For me, It was a gradual process, and to be honest K-pop groups weren't the ones who drew me in. It was the solo artists who did it for me. The first time I ever loved an OST, was when I watched DOTS. So I went and added those songs to my playlist. After that I kept listening to OSTs I liked and eventually began to venture into K-pop groups. And here I am, still venturing and still trying to find a group I really like. So far, I really don't have any extreme biases, but I think it might happen sooner or later.
