SHINee's Key explained why he's against doing the 2x dance on 'Weekly Idol'.
On June 13, SHINee guested on the idol show. MC Lee Sang Min commented, "Before the recording, Key said he would do everything except the 2x dance."
Key responded, "It's not because it's hard but so many groups have done it and we don't even have any more songs to try the 2x dance. I was wondering what we can do differently so I said I would do everything but the 2x dance."
As a result, SHINee skipped the 2x dance and tried the new roller coaster dance challenge.
