Some comebacks were so good and iconic... but the feelings you felt while seeing it for the first time won't be felt again as the song ages. Once you ease into the comeback being a thing, it's easy to forget how good it is.
Keep in mind, your memory of the songs will be erased so it will feel new to you.
Here are some comebacks I'd would go back and see for the first time:
(Not in any particular order)
-Replay by Shinee
-Fancy by Twice
-Feel Special by Twice
-As If It's Your Last by Blackpink
-Monster by Exo
-Deja Vu by Dreamcatcher
-I Need U by BTS
-TT by Twice
