Ok then..
Prokofiev "Romeo and Juliet" a bit harder work though...
Mendelssohn "A Midsummer Nights Dream" Young prodigy, simple but instantly like-able
Rossini's Overtures.. Great fun!
Vaughn Williams, Fantasia on "Greensleeves" "Tallis" If you like thick stringed beautiful pastoral pieces.
Try a Bruckner Symphony? his 4th (romantic) or his 8th (considered by many to be the romantic era's best symphony)
How about a bit of 20th Century easy listening... Phillip Glass "Violin Concerto No 2" or John Adams "Harmonielehre"
If you are feeling a little spiritual, try some Arvo Part " Best of" or "Portrait"
Or.... if you just want to cut to the greatest of all.....(that covers all of the above in emotion, technique, and so much more) Then just spend time listening to Beethoven's 9th Symphony from start to finish. (I would recommend Karajan Conducting 1962)
