My favorites are Good Days, bbi bbi, and Blueming. Although these songs are very popular, everyone knows IU more as a singer. Few people know that she has such a strong singing ability and has so many good songs. In fact, IU's main job is as a singer, and acting is just a side job for her. But even as a sideline, she has delivered many TV series with high ratings.

When it comes to IU, we have to mention the good days when she demonstrated her superb skills in three-stage high notes. This is one of IU's famous songs. After the song "Good Days" was released, it caused shock in South Korea. A 16-year-old girl actually had such high singing ability, which also laid the first step for IU to become famous. This song mainly expresses IU’s youthful crush as a young girl. But her age was quite suitable at that time, because IU was just a teenage girl at that time. It vividly expresses the feeling of a girl who wants to get close but is afraid to get close to the person she likes.

The second is bbi bbi and Blueming, both of which are IU’s songs in recent years, and they are also divine songs on Douyin. People who frequently use Douyin will hear these two songs. Many people use these two Korean songs as the background music for their own videos. But many people may not know who the author of this song is, but it is actually IU herself. The melodies of these two songs are very light, and you can hear that the singing skills are still very high. It is no wonder that they have gained such high popularity.

IU is a very capable singer. Her singing ability is widely praised in the Korean singer circle. When many people participate in talent shows, they will choose her songs to show off their singing skills, because IU's songs are generally difficult to sing. Although IU has shifted more focus to her acting career in recent years and achieved good results, I personally hope that IU can bring more good music works to everyone.
