With SNSD's Tiffany and Yuri stepping down from their MC roles on Music Core, the MBC music program is still looking for full time MC's to replace the girls. Until then, they're going to use one-time MCs. Last week, SHINee's Onew and f(x)'s Krystal filled in, and this week, the JYP family will step in as well. 2PM's Nichkhun and miss A's Suzy will be this week's Music Core MCs. This week is another summer special, so they have an important job as MCs. The big news is that Onew and Krystal will be there as well. That's right. This time, there will be four Music Core MCs. Do you think that'll be a good idea or will it be too messy?
