The song was first uploaded on September 24, 2009; and is DATEKEN's 11th original work. His previous was his hit, "Namae no Nai Uta" uploaded a month before. Ur-Style became somewhat notable and like several of DATEKEN's works, reached the Hall of Fame (exceeding 100,000 views).
A year after the song is uploaded, on November 15, 2010, DATEKEN uploaded a remix for the song titled "Ur-Style -arbitary style-", though to date the original is more notable and has more derivatives compared to the mix. It's also later mixed in DATEKEN's "d a technology mix" album as well.
DATEKEN mentioned in his description that Ur-Style is a techno pop song. He was inspired by Watapon (it's said that he was looking through his illustrations; presumably in Piapro) and he suddenly got an "image" of what to compose. DATEKEN also said he tweaked around with auto tune and the video editor on making the song. Overall Ur-Style tells a story of deeply "listening into music".
