I would agree with A, but the point distribution is just too severe.
18 - 15 - 12 ... 9, 8 etc
For example, one person with a very different taste in music now has as much points for his first place as two users giving a fourth place to a song. The combined vote is probably going to be the Top 3 of every juror, with some combined effort getting the low 3,2,1 points.
If we're going with this change, I'd advise 15 - 13 - 11 - 9,8,7 etc system, that way two users giving a 5th place to a song would be one point higher than someone's first pick, but 15 points would definitely be enough to get into that top 12.
I have the combined vote of Italy back when I hosted. 4 users participated. 15 points would be in sixth, so 18 points is definitely a bit too much for the standings.
