Those are some of my favorites!
Most of my favourite 4minute songs, except for volume up, don't have MVs so I'd assume you've not heard most of them
I want to watch some more Gayoon variety shows, but the problem is she isn't really in many. (Only one I've seen her in was Chuseok sweet girl special which had every member of 4minute in it, except kinda not Hyuna since she was only in the first part, but it also had like 20 something girl group members in it so didn't see her much)
Hyuna was awesome in Invible youth though.
