MELISSA BLOCK, HOST:
And now to a classical takedown.
(SOUNDBITE OF MUSIC)
BLOCK: That's Pachelbel's "Canon in D," and it appears on one of the hottest releases of the year, "Fifty Shades of Grey: The Classical Album."
ROBERT SIEGEL, HOST:
Yes, the classical album. It's composed of works that inspired author E.L. James while she was writing her steamy best-selling trilogy. And it has spent 11 weeks on Billboard's Classical Traditional Albums chart, 10 of those in the top slot.
