DESCRIPTION:
EDIT: Some people have indicated that Dongmyeong's line at 3:30 is actually Chan's - I think this might be true, so if so the rankings are as follows:

1. Chan - 36.3 sec ↑1
2. Jun - 34.8 sec ↓1
3. Hansol - 31.0 sec
4. Hojung 25.9 sec ↑1
5. Dongmyeong - 22.1 sec ↓1
6. Hangyul - 19.7 sec

The winning group for the fourth mission "Digital Singles Release" consisting of Lee Junyoung (U-KISS), Lee Hangyul (IM), Go Hojung (HOTSHOT0) Kang Yoo Chan (A.C.E), Ji Hansol (ex-SM Rookies) and Son Dongmyeong (MAS) was awarded with their very own music video for "All Day!"
