Hearing English spoken with a slight Spanish accent is pleasant to my ears. Some Southern accents are pleasant, depending on the region. Kind of a funny side story: I have a cousin from Australia and she, naturally, has an Australian accent. I am from the the rural Pacific Northwest and we really don't have much in the way of an accent and few regional language distinctions. I asked her one time what we sounded like to her and she said something like "very plain, simple, almost robotic." I'm not sure if we sound that way to everyone, but who knows.
