the mix between danger and error is soooo beautiful

Simply great. That transition from "Insane" to "I Need U" was heavenly, and "Bad" and "Good Boy" sounded so good. My GOD, you are perfect.

3년 전에 케이팝에 눈뜨며(?) 세림님 채널을 접했었는데요. 제가 좋아하는 가수도 언젠가 세림님이 커버하고 싶을 정도로 좋은 음악해주고 성장해주길 얼마나 바랬던지요. 그때의 감정도 생각나고 오랜만에 좋은 연주 쭉 들으니 넘 좋네요 세림님은 어디에 계시든 음악으로 누군가에게 좋은 영향을 주고 계시겠네요. 소소한 응원을 보냅니다~!

The I Need U and Growl merge bit is so beautiful it could end fan wars.

BTOB - Insane and SHINee - replay mix, and then and the transitions over to "i need you" is so freakin god... And error and danger is gold.

I REALLY want to hear a separate cover of BTOB's Insane. But FANTASTIC JOB. I'm still mind blown. :)

1. Big Bang- Bang Bang Bang 2. TVXQ- Mirotic 3. BTS- Danger 4. Vixx- Error 5. Exo- Wolf 6. Block B- Her 7. Btob- Insane 8. I didn't really hear it. 9. BTS- I Need You 10. Exo- Growl 11. Exid- Up and Down 12. Infinite- Bad 13. GD x Taeyang- Good Boy 14. B2st- Good Luck 15. AOA- Heart Attack 16. IDK 17. Girl's Day- Expectation

2019 anyone?soooo amajinggg 👀❤ i need 2016,2017,2018 & 2019 mashup 🔥

Well. Dang girl you just blew my mind!!! Btw the songs fit really well with each other!

You're a freaking genius my friend! I didn't looked at the screen, I was sketching something, and everytime I hear my favorite group's song, I get distracted! Like Vixx Error, BTS danger and I need u, Exid Up and Down, Infinite Bad, BtOb INsane, Girls Day Expectation, Exo Growl and WOlf LIKE WOAH YOURE AMAZING New subscriber here!

갑자기 삘 받아서 세림님 피아노 영상 다 들어보고 있네요ㅎㅎ 중1때 스마트폰 생기면서 유튜브하다가 알게됐는데 그 때 접한 세림님 피아노영상은 정말 황홀했습니다ㅎㅎ 그땐 또 별빛이었을 때라 제일 좋아했던 피아노유튜버셨는데 언젠가 이 영상이 알고리즘의 선택을 받아 많은 사람들이 볼 수 있었으면 좋겠습니다!! 응원해요

누난 너무 예뻐만 빼고 다 들었어요ㅠㅡ 볼때마다 믹스 진짜 자연스럽게 잘하시네요!! 예전부터 영상 쭉 봐왔던 팬입니다 항상 존경해요!!

진짜 소름이네요~!! 항상 영상 올라오는거 너무 너무 잘보고 있습니다~!! 진짜 너무 너무 멋있으세요!!!bb

There were just way too many emotions for me when I listened to this. I was doing some work while listening to this and the feels crashed into me.

노래 듣기 전에 꼭 눈 가리시고 몇 곡 맞추시나 해보세요! ㅋㅋㅋ 제 블로그 이웃 분께서 무려 16곡을 맞추셨는데 17곡 다 듣는 분이 계시나 너무 궁금해요!ㅎㅎ 몇 곡 들으셨나요?? I'm really curious if anyone can hear all 17 songs without looking at the video. Let me know how many you heard!!! :D

You have an incredible talent, I hope to one day be as good at playing violin as you are at playing piano. :) This is honestly mindblowing and I don't know if I'll ever make it to your level of skill, but when I listen to your arrangements it always encourages me to improve. Thank you for being amazing!

Fantastic job,I think this cover is the best!^^

Absolutely amazing!!

동방신기 미로틱 연주 감사합니다!♥

#hacked by his daughter. its the best mashup ever! i love it

AMAAAZIIINGGG😍😍😍 THE I NEED U PART THO~ ㅠㅠ💕

congratulation! it's awesome! :) i can't stop listen this

Do you even know how talented you are??? Unnie!! Oh my goodness I've been playing the piano for years and I don't think I'd ever be able to do that! Could you do a cover of TVXQ's Catch Me?

OMG! Love the way you play piano!!

You are soooooo amazing. when you played Shinee- Replay was brilliant. it was a bit soft though i had to replay it over again just to hear it properly. Luved it when BTS-Danger and Vixx- Error came in together. However I couldnt figureout when EXID up and down with AOA heart attack played. didnt seem in sync. but then i could be wrong.

I love that you included BTOB in this!!

우와~ 이 곡들이 다 믹스가 되었는데도 음이 좋아요. bb

This is amazing 🙌🏻 hands down better than anything I can do

우와 진짜 멋있어요 팬이에요 ❤️

와 정말 감동먹었어요 진짜로 누나가 연주회에서 치면 일어서서 박수를 받을것 같네요~^^

This makes me want to take piano lessons. Just watching others on KZfaq give lessons is too frustrating. You're really good by the way👌🏼

That was so gooooooddddd! 진짜 좋아~!!
