After each mission on MBC's hit program I Am A Singer, the mission tracks were released on music portal sites and have received explosive attention as the songs have all reached a high position on the music charts. Notably, the winners for the last two missions, Yoon Do Hyun and Kim Bum Soo, had all-kill's with "I Will Always For You" and "Please". This is an incredible feat that most veteran singers couldn't achieve. With such popularity, a representative from the music industry revealed, "They most likely profited around 100,000,000 WON (around $100,000USD) in a single day from the digital sales alone." Currently the plan is to donate the profit from the sales to make improvements in the Korean music industry. Source: mydaily
