I have tried also to expand my horizons in music over time ... I still like the favourites of mine: The Beegees, Karen Carpenter, John Denver, Robert Goulet, Doris Day, etc.
Some neo-classical is now on my listening list ... mostly organ neo-classical. I also enjoy using more contemporary composers in organ music, Camille Van Hulse, Flor Peeters, David Johnson, Randy Runyon, Carl Best, Max Reger (to a limit on Reger - some of his stuff is way beyond my means of capability and/or lack of instrument resources.
Of course, anything Frederik Magle composes is right up there next to Buxtehude ... as well as the works of another resident organ composer, Jean-Paul Verpeaux (aka Musicalis)
