YT: In the skit before the Stars of the Saga talk show at Star Wars Weekends 2014, Stormtroopers danced to their favorite playlists from Earth featuring today's popular songs like Let It Go from Frozen and What Does the Fox Say among many others.
It's not quite the Dance-Off With the Star Wars Stars from Hyperspace Hoopla - which isn't performed anymore - but it's the closest the event has to it in 2014.
