Fiona Apple 'I'm in the Middle of a Riddle' (ft. Maude Maggart) (Anton Karas cover)
Ahead of Valentine's Day, Starbucks has unleashed another sneak preview of their love-stricken, covers-based Sweetheart 2014 compilation. This time, the ooey-gooey sentimentality is served up by Fiona Apple and her cabaret singer sister Maude Maggart, who offer up a new version of Austrian composer Anton Karas's "I'm in the Middle of a Riddle."

An old-timey cheer courses through the cover, with the sisters delivering doe-eyed harmonies atop mandolin strums. Whether or not their respective loves have been struck by cupid's arrow is the riddle in question ("Though I show I love you so, I've got a feeling you're concealing something that I ought to know").

You can stream the pleasantly heart-pumping waltz down below.

Sweetheart 2014 also features contributions from Beck, Vampire Weekend and more. The compilation drops February 4 through Hear Music/Concord Music Group.
