This is the fifth year in a row that the work has topped the list of the 300 most popular works, which the radio station revealed to the public over Easter weekend.
Ralph Vaughan Williams' A Lark Ascending came in second place—and was the top-ranked work by a British composer—and Mozart's Clarinet Concerto in A came in third.
Max Bruch's Violin Concerto No. 1, now in fifth place, held the number-one position for five years, until the Rachmaninoff concerto took the spot in 2001.
Mozart works took the most spots on the list, with 21 entries. The British composer represented by the most works was Edward Elgar, with 11 entries. Karl Jenkins had the most entries, at three, by a living British composer.
Station manager Darren Henley said, "As the largest poll in the public's classical music tastes, it's fascinating to see how works fall in and out of favor."
