Changing them to "YEAR Weekly Number 1 Singles" would be a good bot thing, if nobody objects to the renaming. With this it's possible to make renaming categories nearly as simple as renaming other pages, just slower to process.

Splitting up the daily number 1s by year would pretty much need to be done manually--it might be possible to somehow get the intersection of "Daily Number 1 Singles" and "1999 Singles" and know which pages to add "1999 Daily Number 1 Singles" to, but since there only average out to be a few per year anyway that would probably take just as long.

If we do these, maybe this would call for another intermediary level of category. Right now it's like But with two sets of categories split by year, rather than them all being lumped together it could be like
 * Number 1 Singles > 1999 Number 1 Singles
 * Number 1 Singles > Daily Number 1 Singles
 * Number 1 Singles > Weekly Number 1 Singles > 1999 Weekly Number 1 Singles
 * Number 1 Singles > Daily Number 1 Singles > 1999 Daily Number 1 Singles
