Many pieces by Tchaikovsky.

Most pieces by Shostakovich (to quote Boulez, he's just a second or even third pressing of Mahler), Rachmaninoff (so terribly bombastic, clichéd and sentimental it hurts), Barber and Britten.

Almost anything by those retrogressive American contemporary composers of neo-tonal schlock that are so popular nowadays, e.g., John Adams (especially his terribly kitschy 9/11 piece that won a Pulitzer Prize), Corigliano, Kernis, Joan Tower, etc.
Anything Philip Glass wrote after "Einstein on the Beach".

Anything by Sibelius and Ralph Vaughan Williams (two completely uninteresting and incompetent composers).

All pop music.
