After smashing national and international musical records, IU surprised fans on her birthday with a new version of her song Eight. The original song released a couple of weeks ago with BTS singer Suga rapping in one portion of the song. While the ARMY and K-Pop fans are streaming the song on various musical platforms, IU decided to bestow fans with the acoustic version of the song. The new version doesn't feature Yoongi but IU includes the Bangtan Boy by singing the rap he sings in the OG.
