Big changes on 04/12/2018

Alkadikce Today something strange happened to the list. For about two months since I am here on TheTopTens, the top ten songs were always the same (current place of the song in brackets):
10. Like a Rolling Stone (15)
9. Sweet Child O' Mine (9)
8. Hey Jude (8)
7. Comfortably Numb (6)
6. One - Metallica (5)
5. Hotel California (7)
4. Smells Like Teen Spirit (4)
3. Imagine (3)
2. Stairway to Heaven (2)
1. Bohemian Rhapsody (1).
I remember the top 20 yesterday and they changed their order completely. There used to be slight changes but not to this extent. Current position in brackets.
20. Satisfaction (32!)19. Hallowed Be Thy Name (14)
18. Fade to Black (12)
17. Billie Jean (19)
16. Master of Puppets (10!)
15. Wish You Were Here (18)
14. November Rain (16)
13. A Day in the Life (11)
12. Free Bird (18)
11. Lose Yourself (13)

Songs lower on the list have risen or fallen thousands of places. It seems that a couple of votes and remixes were calculated in the result this day. Can you think of any reasons behind phenomenon?
