Accents are a part of life. We all have one, even though a lot of the time people from the US like to forget that there is such a thing as an American accent. It's embarrassing but a lot of us consider the way we speak to be neutral and anything else is considered a twang or whatever. It's probably because a lot of mainstream music is usually sung with an American accent (If it's in English of course), or because of the many famous American TV shows.
Surprisingly, the generic 'American Accent' is not on this Reddit list, but if you have something else, yours might be.
