Even though many people have mentioned this song, I still want to write about this song.
This song is called “我的滑板鞋”， it was originally created and sang by a guy named 约瑟翰·庞麦郎. When I first heard that song, it was sound so funny to me. 华晨宇rewrote this song in the 巅峰之战 and mixed with some hip pop elements. It was so great song! It totally changed the song! If you have a chance, compare with the song. You will see how talented华晨宇 is！
Thanks! @alvin0617 posted the original track too. Talk about a Karaoke singer heh.
