I voted Tchaikovsky, since he is definitely my favourite composer, and because I couldn't vote for more than one.
other good composers are Vaughan Williams (listening to at the moment), both famous Strausses, Elgar, Shostakovich, Stravinsky, Sibelius, Rachmaninov, Grieg, Saint-Saens, Rimsky Korsakov, Prokofiev, Mussorgsky, Mahler, Holst, Lilburn (NZ composer), Britten, Gershwin, Dvorak, Brahms, Borodin, Bizet, Lizst, Beethoven, and Janacek.
I have more than 250 hours of this kind of music:D
