here's a full list of 90s songs that spent more time at #1 in the UK than this:
bryan adams - everything i do i do it for you
wet wet wet - love is all around
whitney houston - i will always loev you
shakespears sister - stay
meat loaf - i'd do anything for love
celine dion - think twice
robson & jerome - unchained melody
spice girls - wannabe
cher - believe
snap! - rhythm is a dancer
michael jackson - earth song
puff daddy - i'll be missing you
run dmc - it's like that
all household name tunes to this day pretty much. then there's babylon zoo with 5 weeks at the top. baffling to think about, what a weird time for pop music. even the vaguely related 'blue (da ba dee)' which seemed to be absolutely everywhere for months only spent 3 weeks at #1 to babylon zoo's 5. i also noticed recently the verses in 'blue' sound exactly like korn lol
