What song do you wish everybody could sing perfectly?
Perfectly topical for this time of year, I suggest Auld Lang Syne' by Rabbie Burns. This does grate on my ears (and yes, I am Scottish, proud to be so), but the the word is Syne', not Zyne'. This time, on BBC 1 Scotland, we had a singer who could pronounce it correctly. First time in years. And it's simple, pronouncing an s' instead of a z'. We're not doing anything difficult like asking you to pronounce the word loch' instead of lock'.
