Weekends on All Things Considered continues its "Why Music Matters" series with Olympic luger Christian Niccum. Niccum says music was the key to one of his first accomplishments in the sport.

"I was 15 years old, in Berchtesgaden in Germany," he says. "It's the oldest artificial luge track in the world, and it's also the most difficult."

When Michelle Obama's great-great-great grandmother was 8 years old, her life underwent a dramatic change.

Melvinia Shields was a slave who grew up at a South Carolina estate with a relatively large community of slaves she knew well. But then she was moved to a small farm in northern Georgia where she was one of only three slaves; most white people in the area didn't own any.

On a week monopolized by important political news, many of you still took time out to comment on our National Geographic inspired poll, which asked "Which president, would-be president or movie president would do the best job if extraterrestrials come to visit?"
