"Welcome To The Jungle" was not released as a single by NRG in 2012.
While Chun Myung-hoon was once a member of NRG, the text says "He released his single, "Welcome To The Jungle" on October 19, 2012" -- so he did not release it with NRG in 2012. The band combined the fact of his band membership with the single.
