Singer Oh Soo Min has thrown out a letter of challenge to Lee Hi.

She started on the 21st, writing,

The hottest person now, Lee Hi. I think she's a soul singer like me, but.. mm... I don't know. I don't know about anything else, but I want to have a battle with her with just vocals. I want to go with the recently popular method, pick about five songs and sing the same songs to battle each other. I want to leave the judging to the people who are listening to it real-time, and we'd just battle with each other through pure singing. I'm pretty confident about my singing... I don't know how you'd feel. Both sides can decide on the medium... or you can decide. Wouldn't it be fun? I guess she might not do it because she can lose big. Anyway, I'm giving you a suggestion. With that in thought, I sang her recent song. I'm not saying you have to sing like this...^^

First, I didn't know I'd get this much attention. My suggestion was the musical swagger that comes out often in music. I'm not saying that she's worse than me because of that, but it was more of a vocal game that was 'I'm this good at singing, so do you want to have fun and battle?'. I'm a person who only knows how to sing, so I thought we could have fun singing. If this really happens, I thought we'd be able to show a fun, new culture for the public. I was talking about an on-spot battle that instrument players and vocals actually do, and even now if that side agrees to the suggestion, I want to do the battle. I don't think the losing side will disappear from the world as a 'Bad Vocal'. I'm sorry if anyone felt uncomfortable because of the way I talk. Please think of it as a way to make a fun culture. Thank you.
