Here are the same songs but at the KBS song festival! I vastly prefer this arrangement of Idea, though MAMA 2020 also had great performances by him.
One of my other favorite performances from this festival was a dance line cover of GOT7's Hard Carry. It's a fun song! Shame the GOT7 reaction to this stage was taken out haha, it was hilarious.
This is less of an 'epic moment', but someone commented that this rendition of Like A Fire is like all of them having a group project that they're being graded individually on lmao. Key's high note at the end and Jjong and Onew singing back and forth at each other while Minho dances in between them and Taemin just stands and watches from the side...truly A Moment. Also, Replay at SHINee World is very moving - love this performance. It's their first song, so them performing it on this giant stage for such a large crowd was a very emotional moment for the members, and the performance is really beautiful.
Honestly, this post is mostly SHINee anyways so let me introduce y'all to Woof Woof too - it's truly something, that's for sure. Key's very dedicated to his performance here! Some people love it, some hate it haha!
