Fans of the best original song Oscar hopeful "Lost Stars" — which was co-written by Grammy winner Gregg Alexander (who I recently profiled) and performed in John Carney's charming indie Begin Again by Adam Levine and Keira Knightley — were down in the dumps last Thursday after it was left off the list of the Hollywood Foreign Press Association's Golden Globe nominations.

But on Monday, their spirits — and perhaps the song's Oscar hopes, too — were lifted in a big way when the film landed two major moments in the spotlight: a best original song Critics' Choice Award nom and a primetime, three-minute live segment on an episode of one of the most highly-rated shows on television, NBC's The Voice.

As you can see in the video below, contestant Matt McAndrew and his coach, Levine, performed a rousing duet of the song, which was met with a huge ovation.

Dec. 16, 5 p.m. The McAndrew/Levine version of the song has broken into the top 10 most downloaded songs on iTunes.
