Music sales may be low but interest in music isn't, at least according to the ratings for the Grammy Awards.

Nielsen Media Research says that Sunday's ceremony was seen by at estimated 19.1 million people. That's about two million more viewers than for last year's show and higher than it's been for three of the past four years.

Among young viewers ages 18 to 34, ratings were up 23 per cent.

The Grammys tried to reach a mixed audience, with a duet featuring teen dreams the Jonas Brothers and Stevie Wonder. Last year's Grammy Awards, with 17.2 million viewers, was the least-watched Grammys since the awards were first televised by CBS in the mid-1970s.
