Though KBS 2TV's 'Immortal Song 2' has a loyal fanbase, it just wasn't enough to stop the ratings freefall this week. According to AGB Nielsen Media Research, the show's latest episode (aired on November 26th) received a viewership rating of 7.9%. In comparison, last week's episode garnered 10.7%. The statistic was a shock to the program's fans, who expected the new cast to positively affect the ratings. K.Will, SG Wannabe's Lee Suk Hoon, Brian Joo, and Davichi's Lee Haeri joined the cast this week in covering songs from veteran artist Lee Kwang Jo. 'Infinity Challenge' and 'Star King', which aired at the same time, received 17% and 11.1%, respectively.
