"In my father's case, I think he's going to die onstage and I respect that very much," the 32-year-old pop star said of the 64-year-old. "In my case, in 15 years I'll probably look ridiculous singing 'Bailamos' ('Let's Dance')."
The Madrid-born artist - who debuted in 1995 with a self-titled album and releases a greatest hits compilation "95/08" on March 25 - said dissatisfaction with his own work is what drives him to continue performing and recording.
"When I listen to my music I think it can still continue to evolve," he said. "After a couple of months go by, I think I could write a better song."
Iglesias said he is striving to make the perfect record - "One you listen to 10, 15, 20 years from now and say, 'Oh! I wouldn't change a thing."' And until Iglesias makes that album, it seems nothing is set in stone.
"I want to retire in the next 15 years," Iglesias said. "But that's what I say now. Who knows if I'll have the courage to do it when the day comes."
