NEW YORK: Tony-winning Idina Menzel — or Adele Dazeem if you’re John Travolta — is enjoying massive success with “Let It Go” from the animated film “Frozen,” but the entertainer is still perplexed that she’s finally triumphing on the pop charts with a show tune-esque track.

“I’ve had a lot of self-introspection about this. This business is so hard, especially the music business, and I’ve tried so hard to crossover, to convince people just because I was in a Broadway show I didn’t have the street cred to be a rock or a pop singer,” she said in a recent interview. “And then the one time I have it, it’s the arrangement from the Disney movie.”

“I’m singing at the Oscars — I’ve never sang at the Grammys,” Menzel added, laughing.

Menzel’s musical moment grew even stronger when “Let It Go” won best original song at Sunday’s Academy Awards (the Oscar went to the songwriters and producers, Robert Lopez and Kristen Anderson-Lopez). The song has sold close to 1.5 million tracks and is a Top 20 hit on the Billboard Hot 100 chart. The “Frozen” album, a platinum success, is the soundtrack to spend the most time at No. 1 on the Billboard 200 chart with five weeks and counting; it recently beat the record set by the “Titantic” soundtrack, which featured Celine Dion’s epic, Oscar-winning “My Heart Will Go On.”

“I’ve had ups and downs ... and I’m aware of when something’s happening and has an energy of its own,” said Menzel, who voices the lead character Elsa in the film, which won the best animated feature Oscar. “I’m aware enough to know of something special and to try and be in the moment.”

Menzel is having more than a moment in music though, thanks to Travolta, who uttered “Adele Dazeem” at the Oscars instead the singer’s name. He has since apologized.

The 42-year-old does plan to record more music, but right now she’s focused on “If/Then,” the new Broadway musical she stars in. She will play the role of Elizabeth, a women returning to New York City to rebuild her life after a divorce, and she’s been rehearsing for weeks at the Richard Rodgers Theatre, where she has nicely decorated room — or mini apartment — set up to help make her comfortable since the show begins previews Wednesday and officially opens March 30.
