Ysha, a co-intern of mine introduced me to a cover made by Taylor Swift on her latest album "Speak Now". Her take on Viva la Vida by Coldplay is really cool. Check out the differences or similarities here. And wait there are still other covers made by other artists aside from Taylor Swift... Boyce Avenue and Lady Gaga covers.
