It sounds like "Hooked On Classics" was made for the likes of you. These albums consist of medleys of selections from classical music. You're bound to hear music you like, and especially music you'll recognize (I was obsessed with old Warner Bros. cartoons when I got my Hooked cassette and recognized much of the music from those), and you can look up the piece title and composer in the liner notes to discover more once you find something you do like.
Hooked was also often used in schools to get kids interested in classical music.
