LOL, Classical music? Actually I think the best advice is by those who suggest you look in your local library or listen to a local radio station that plays classical music, it is too varied. There are different periods of Western Classical music. You might like Gregorian Chants, Renaissance, Baroque, Classical era, Romantic or Modern. Another recommendation is to get a book on the Great Composers to develop an appreciation of the era they lived in and why they were considered great for the period they came from. Typically these books list many of the works and masterpieces they created. One example is "The A-Z of Classical Composers" by Peter Gammond. Not too heavy but quite informative. There are others that list recordings that are considered definitive, not because of recording quality but performance. An example is "101 Masterpieces of Music & Their Composers" by Martin Bookspan.
Ultimately it will come down to what peaks your interest. When you decide which music sounds good to you then you might ask for specific recommendations so far as recordings.
