Likes and dislikes of languages are dreadfully subjective things. Many don't like German because it's so guttural. For me that's one of the beauties of the language. Some like French; why I'm not sure. I find it very irritating with its nasality. Purely personal prejudice. I don't say that people who like the sound of French are wrong and I would expect they not say that I am wrong for liking German.
