I just found out that good quality chocolate contains about five hundred different flavors. That's way more than any other food we eat. This is exactly why you're supposed to eat it slow. I know, it's hard to resist eating it fast. I have a hard time with that myself. But if you really want to get the full range of flavors you'll want to let it melt in your mouth and savor it. Given time, your taste buds may be able to identify all of those flavors, but you probably won't be able to consciously distinguish them.
