We reported earlier about SNSD's involvement with the OST of the new MBC drama Heading To The Ground, starring TVXQ's leader Yunho and Go Ara. Last week we brought you Taeyeon and Sunny's ballad duet, and now we bring you more members from the SNSD crew in "Motion"! The song is slightly different from their usual stuff but it's jam packed with pep and e"motion"!
