The new Korean band 2NE1, Jeon Ji Yoon from 4 Minute, sang an Unbrella cover originally sung by Rihanna. Excuse their English accents. Jeon Ji Yoon did it w/the original Jay-Z during the intro(an instrumental) and 2NE1 had the group leader CL rap Jay-Z's part.
Jeon Ji Yoon's Unbrella:
Personally I enjoyed 2NE1's version more. I thought it was more unique how they didn't use Jay-Z's voice, plus i <3 Park Bom!
