Probably around fifteen years ago, I saw a commercial set to - I think - the "Trololo" song (or, if not, a classical song). I think it was a commercial for M&Ms, but it was at least for a similar candy - lots of small bits in a candy shell. The candies were CGI and bouncing in time with the music in a sort of liquid fashion. I haven't been able to find this commercial since!

Sorry for the vagueness. It was a long time ago. Hopefully someone can give me some guidance - thanks in advance!
