Maelstrom

Bach was a great composer, no doubt, and it isn't wrong to exclusively listen to him. But seriously, the majority of his pieces are short and focus on the rythmic aspect of music. In my opinion, this style doesn't... carry me in my emotions. Mozart and Haydn lack emotional harmonies as well. So, I think you should try listening to some Dvorak, Tchaikovsky, and Brahms. This will give you a good idea of the importance of chords. Then, work your way back to Beethoven. I feel that his music is the perfect balance between harmonious and rythmic complexity.
