Help me find that drama.

So here I am trying to respond to someones question. They were on the hunt for dramas that are in the mystery genre. So the one of the first things that pop into my mind was this drama, and I cannot remember the name for the life of me. 

It's a mystery/romance drama. The FL is drummer for the orchestra. She lost her memory (I think) after the murder of her friend. The ML is convinced that she is the girlfriend of his brother (the one that died) and that she is the killer. They eventually fall in love and find the real murderer. 

I've seen it several times before, and I even searched through my whole entire watchlist, hoping that a name would pop out. But I can't remember. So help would be appreciated if you have seen this drama. I'm sure it will come to me eventually, but for right now... I can not remember. ?

I've subscribed to this thread because the Drama sounds (a) vaguely familiar and (2) quite interesting. I hope someone finds it! ?

Oh my goodness, after looking through my watchlist one more time, I found it! ? It's called I Wanna Hear Your Song. It's definitely worth the watch.
