London, England (CNN) -- Canadian rock singer-songwriter Bryan Adams says the secret to a hit song is "a great melody and a simple lyric."
Asked why he thought his 1991 super-ballad "(Everything I Do) I Do It For You," was such a mega-hit, Adams said the song's lyrics had "a universal simple message."
"That's probably the reason why it was a hit in every country in the world," the Grammy Award-winning Adams said on CNN's Connect The World.
The song, featured in the movie "Robin Hood: Prince of Thieves" starring Kevin Costner and Alan Rickman, topped the charts in numerous countries, including the U.S., the UK, France, Australia and Germany.
It spent a record-breaking 16 weeks at number one in the U.K. singles chart.
Adams, who recently turned 50, just wrote a new film song, entitled "You've Been a Friend to Me" for the Disney movie, "Old Dogs," which will soon be released.
"I've worked with Disney on and off for a little less than 20 years," Adams told CNN. "The first thing I did was the Three Musketeers."
In recent years Adams has also become known for his photography and posts photographs on his blog every day he's on tour.
"I occasionally do a bit of photography; it's kind of a sideline thing," he told CNN. "For example, I'll be in Minneapolis on Friday for my American shows and every night I'll post a photograph which represents what happened during the day."
Asked what was the biggest change in song-writing since he started more than three decades ago, Adams answered the downloading of music off the Internet.
"It's quite interesting that none of the songwriters are standing up and complaining about it," he said.
"None of the new songwriters coming up are ever going to make the money of the old songwriters," Adams predicted. "I wish there was a coalition of people that would stand up and help the young songwriters."
Adams said it's "very very difficult" for bands to make money anymore unless they're a touring band. "A lot of people think that music is free now."
Asked what else had changed, Adams answered: "I'm really glad cassette tapes are gone."
Adams told CNN he had tour dates booked in January in Ireland and hoped to be at the opening of the Vancouver 2010 Winter Olympics in February.
