If You Could Have a Kpop Group Cover an OLDER Song...?

I remember when I first got into Kpop that I loved seeing groups covering each others songs and over the years I've seen more variety pop up here and there. Some of the covers of Michael Jackson's songs stuck in my head and I started to think about other older songs that might be fun to see Kpop groups cover.

So, what would you have any girl group and any boy group cover? (You can pick multiples if you want!)

I think it would be fun to hear Wonder Girls sing "You're So Vain" by Carly Simon

And maybe Super Junior with "Hey There Lonely Girl" by Eddie Holman (or maybe TVXQ)

What would all of you pick?
