For those, who don't know, Super Junior-T was a sub-unit of Super Junior that featured some of the oldest members. (Super Junior-H was also like this, but featured Yesung and didn't feature Heechul)
And the T stands for trot.
Well... this is a song that I think has some fun lyrics.
It has a lot of palindromes like: "수박이박수" and "다시합창합시다!"
It's like if someone made an English song that was like: "No lemons, no melon. Taco cat."
and the title of the song is backwards for "거꾸로", which means "backwards"
so it is like if someone titled their song "sdrawkcab"
According to Wikipedia, Yoon Myungsun, Eunhyuk and Shindong wrote the lyrics. (Yoon Myungsun was also the composer)
There is also a Japanese version of this song, where the title is "Rock & Go" and is a pun on the number 65.
I'm not sure if this one has palindromes too.
Well... the title is a play on words though.
