Earlier, we've reported that TVXQ would be releasing two editions of their "Keep Your Head Down" album: a 'special edition', which included 11 tracks and a 100-page photobook, and a 'standard edition', which will include an extra track. SNSD's Seohyun will guest on TVXQ's newest track, "JOURNEY", which can be heard when the 'standard edition' hits shelves on January 12th. Representatives of SM Entertainment stated, "On the 5th, the 'special edition' of their album was first released along with a 100 page photobook.  The 'standard edition' will feature one additional song titled 'Journey' with the help of SNSD's Seohyun." They continued, "'Journey' is a song that expresses the excitement of going on a vacation with someone you love.  Fans will be able to hear the harmonization between TVXQ and Seohyun." The standard edition will also consist of new jacket album photos that were not included in the special edition. Source + Photos: Star News via Daum
