Classical music is the favourite import. Thomas Tallis, Ralph Vaughan Williams, Edward Elgar, Mozart and Beethoven are particular favourites for the Queen, Eileen, L'Evallier, Melanbury and the upper classes generally.
Eileen is a fan of easy listening as well. While she was still in the realm, the Queen tolerated this and grew to like groups like the Carpenters herself. L'Evallier and Melanbury will only listen to classical music. For them all of the arts must be classical. Anything else is just common (that element appeals to Eileen a lot, mainly because it annoyed L'Evallier).
