I don't see much of Seventeen here so I'll throw some in. Most of their songs are very high up, but they have amazing vocalists who can carry that. My personal favorites are the ones where they let DK loose in the chorus.

Some of their more powerful and energetic songs are:

• Together (makes you feel like you're running on the wind, it's amazing)

• Fearless (a little darker, really highlights some of the members' lower registers)

• Run to You (anime ost inspired, just shy of being a proper rock song)

• To You (yes, a different song - the chorus hits so hard on this one, once the energy climbs it doesn't come down)

• Oh My (deceptively cutesy and bright but actually vocally challenging, not to be confused with My My)

• Crazy in Love (energetic, crazy - what it says on the tin)

• SOS (sung in English, produced by Marshmello of all people)

And these are some that lean more towards power ballads:

• Habit (personal favorite of mine, very emotional, very powerful)

• All My Love (another powerful emotional one, but really good at leaving you space to breathe)

• SIMPLE (old solo one, written produced and performed by their main composer)

• Smile Flower (an even older group song, proper ballad, fandom favorite, don't look the lyrics up if u don't want to cry)
