If you hear Tidus' Theme (https://www.youtube.com/watch?v=rsNclYkSWDE) using headphones, around 0:10 there is a clicking noise from the right side.

It's really bothering me.

I hope someone could enlighten me about that sound.

Thanks.

There's no sound like that in PSF2 version.

I don't hear it...

I don't hear it either. Try using different headphones.

I don't hear it at all...
