Have you ever wondered why the "Chocolate Love" song from F(x) and SNSD sounded so familiar? Well, it's been supposed that the background music has actually been derived from another song released a few years back. Former S Club 7 member, Rachel Stevens, released a song called, "Sweet Dreams My LA Ex" which was actually her first ever single. Shall we compare? Notice that the way the song is sung is not similar, but the MR is definitely... Well, alike.
See the similarity?
