The latest episode of Seung Seung Jang Goo (Win Win) was filled with many great moments and here's another one to add to the list. This segment features the boys of 2PM singing 2AM's hit single Won't Let You Go Even if I Die. The 2PM boys did a fine job but 2AM took over and showed them how it's done. 2AM also sang 2PM's hit single Again & Again in a beautiful harmonious voice, those 2AM boys know how to sing! Gotta love the One Day interactions, thanks to Danny for the tip and check out the segment below. Bonus Video dancing to T-ara's Bo Beep
