Have you noticed these weird sounds in EXO's songs?

Music recordings often have all sorts of sounds stacked on top of each other to get the final product. In some cases, they’re virtually impossible to hear, and in other cases, you can hear them if you focus hard enough.

So you think you know all EXO songs inside and out? While most fans would know the lyrics and be aware of certain musical elements of the idol group’s song, what we don’t expect most fans to be aware are the small and yet bizarre details that went into the tracks.

The squeaky sounds that serves as a percussive element of the song. It comes out during the chorus of the song.

You can hear a sheep yelling at around 2:18.

At around 4:15, you can hear a voice saying something close to “xie xie”. The scariest part about this is that Baekhyun once stated in the past that the voice was something that no one had an explanation to and was not intentional.
