MUSIC NOTES: ‘N Sync, Dr. Dre Radio Winners

Dr. Dre won big in Las Vegas, and he didn’t even have to step into a casino to do it. The rapper/producer took home the Legend Award at the Radio Music Awards held Saturday night at the Aladdin Resort.

Creed took home two awards: Artist of the Year and Song of the Year (“With Arms Wide Open”) in the rock/alternative category while ‘N Sync took home the same honors in the Top 40/pop category.

The three-hour event was hosted by the Backstreet Boys, Sisqo and Sugar Ray frontman Mark McGrath.

MADONNA LETS THE MUSIC PLAY: Madonna performed a 30-minute show Sunday at New York’s Roseland Ballroom for what was billed as a thank you to fans. She sang five songs from her latest album “Music” for a standing room only crowd of 3,000. The free show could be a warm-up to her first U.S. tour in seven years next year, Reuters reports.

FROM PRISONER TO CROONER: He’s only been out of jail for three months, but Robert Downey Jr. is all over the entertainment map. The actor is mulling over several film offers, has a recurring role on Fox’s “Ally McBeal” and is about to break into the music business with the release of “A Very Ally Christmas,” a spin-off album to the TV show. It arrives in stores Tuesday.

The recording studio isn’t new territory for the actor. He’s been recording demos since the ’80s. Among the tracks on his debut record? A cover of Joni Mitchell’s “River.”

‘STRAIGHT UP’ FOR DURST: Look out for Limp Bizkit’s Fred Durst, who appears on “Straight Up,” a multi-artist project recorded as a tribute to former Snot vocalist Lynn Strait. Joining Durst on the project are Korn’s Jonathan Davis, Sugar Ray’s Mark McGrath and Incubus’ Brandon Boyd.

Snot was about to make it to the big time with the release of their first record when Strait was killed in 1998 in a traffic accident. “Straight Up” arrives in stores Tuesday.

HER HEART WILL GO ON: The National Enquirer has settled a $20 million defamation lawsuit with Canadian chanteuse Celine Dion. The two parties reached a settlement over a story the tab published that said the singer was pregnant with twins. The story was false and the editors knew it. The tab promised to print an apology and a retraction in Thursday’s issue.
