'Korea's sweetheart' IU recently gave a Starcall to her fans from the recording studio. On December 21st, IU revealed that remixes of her hit track "Good Day" were in the works for her year-end performances and award shows. IU said,

"Because it's the end of the year and there are many award ceremonies, I sang a variety of versions for 'Good Day'. I'm here today to listen to the arrangements/recordings. The weather has gotten very cold and many of you became sick, huh? Please be careful not to catch a cold and since it's Christmas soon, enjoy your Christmas. Though I won't be able to play on Christmas because I have schedules, I will be here and there on TV. Have a merry Christmas while watching me on TV!"
