Teddy has been majorly involved with only 3 yge groups up untill now. Bigbang, 2ne1 and blackpink (arguably the three biggest groups to ever come out of yge) As for bigbang GD did much of the work himself but Teddy had major contribution too... he made songs like Fantastic Baby, blue, eyes nose lips etc. He was the main producer for 2ne1 before disbandment and now of course blackpink.
