Previously on June 28, netizens noticed songs by BTS, IU, SG Wannabe, and Oh My Girl suddenly plummeting in rankings on the domestic music streaming platform FLO.

According to netizens, the rankings for songs including IU's "Hold My Hand", "Eight", "Blueming", BTS's "Life Goes On", SG Wannabe's "Saldaga", "My Person", and Oh My Girl's "Nonstop" quickly began to fall, until they were eventually bumped out of the top 100. All of these songs have steadily held high rankings in the top 100 songs chart for the past month. 

When various netizens filed complaints, FLO released a short statement which read,

"In order to maintain fairness on the chart, FLO uses AI technology which applies a certain logic. However, during a recent feature update, the reformed logic used by the AI system took exaggerated effects, and so such errors occurred. After receiving feedback from users, the system has restored the errors."

As of July 1, many of the songs mentioned above have retrieved their top 100 rankings.
