The song shot to number eight in the UK in 2002 - and reached the number one spot the following year.
And the anthem won a new generation of fans after it was featured in thriller Saltburn last year.
In a book by Jon Kutner and Spencer Leigh titled 1,000 Number One Hits, Bruckner said: "The lyrics say that happiness seems to be loneliness and loneliness killed my world.
"It doesn't really make much sense to me either - but I prefer it because of that.
"I like the idea that it is a bit crazy - it's just that kind of record."
Brit singer Will Young gave a nod to the classic by incorporating its lyrics into his 2015 hit Love Revolution.
Bruckner was also known for his songs The Circle, Prosac and Silence.
He also collaborated with Sonique, Hardwell and Bloodhound Gang's Jimmy Pop during his career.
The iconic DJ released a total of four albums during his life - all within just six years.
