Most of the artists that MBC's producer Shin Jung Soo wants for "I Am A Singer 2" are currently in the KBS 2TV's "Immortal Song 2" idol lineup. On May 24th, producer Shin made an appearance on an MBC Radio program and revealed his thoughts regarding "I Am A Singer 2", saying,

"If a second season is to officially begin, there will be a time in which all of the members will have to be taken up at the same time. One of the cards that may be used in either the second or third season includes having talented young singers such as IU, SNSD's Taeyeon, SISTAR's Hyorin, among others."

Most of the idol vocalists that producer Shin referred to have recently completed filming for their second episode of "Immortal Song 2". An "Immortal Song" production representative stated, "Though we knew that they were very talented, we didn't know that it would be to this extent. Throughout the competition, it was extremely competitive and it was hard to determine who was better. The response from the audience was also explosive."
