However Wikipedia has sources and is rarely wrong. Though I agree we cannot always be 100% sure unless we dig in all the sources.Maxus wrote:
Wikipedia isn't official though, it is a website where literally anyone can edit the information, hence why it's unofficial.
While the youtube link provided by KwaN is directly from the producer company (look at the channel, it has "verified" status in it) and cannot be edited by anyone except the official people , hence why it's official.
The song title on YouTube is written in a way so that everyone can easily search and find it, that is why you have Girls' Generation in roman letters and 소녀시대 in Hangul put next to one another. I wouldn't consider the YouTube video name as a reliable source.
