Which “idol” singer has the greatest singing skills as to appear in I Am A Singer?

In the episode of MBC’s Weekly Idol that airs on the 29th, a list of top ten “idols” who are considered having great singing skills to appear on I AM A Singer will be revealed.
Every week, “idols” participate in survey in the feature called “Real Chart! Idol Self-Ranking.” This week they voted to find out the best successor for Lim Jae Bum who gave great performance on I Am A Singer.
Some “idols” were already approved with their great voices through KBS 2’s Immortal Classics 2; however, there still are other hidden talented “idols” waiting to be discovered, and the fact that this survey is run by “idols” themselves is drawing attention.
2PM, B2ST, Infinite, Brown Eyed Girls, Sistar, and T-ara participated in voting. Infinite’s Woo Hyun, 2PM’s Jun Su, SHINee’s Jong Hyun, and SNSD’s Taeyeon were nominated.
However, Sistar’s Hyo Lyn took first place on the survey and obviously, she is approved with her great singing skills by many of her peer “idol” singers.
Jung Hyung Don and Defcon, the emcees of the show, are to call Hyo Lyn and congratulate her for ranking no.1 on the chart.
