I like the cool house rhythm and refreshing vibe of Impossible.

The repetitive beat is exciting, so there isn't a dull moment while listening.
The members' voices blend naturally with the cheerful rhythm.
I really love how the atmosphere gradually builds up as the song progresses.
The choreography really captures the rhythm, so it makes me want to look up the stage videos.
It is a song that makes you feel good when you listen to it while exercising or going out.
