Oh kids...
Every person in the entire World has an accent unless their group is small and they are the only people speaking their language... such as a tribe of 50 people living in the amazon and they are the only people that speak their language.
So regardless of where you live in the US, you have an accent.
To foreigners, our language does not sound pretty. Our words are fairly harsh but with the inclusion of a significant amount of latin based words into our Germanic based language, it isn't quite as harsh as german/dutch/swedish and the sort.
We emphasize and say letters differently than the English. They have a much rounder version of the language, using the backs of their throats more and rounding their mouth. This provides a more pleasant sound than our front of the mouth and enjoyment of the use of our teeth.
Australians still have the roundness, but can sound a bit more nasaly. A lot of the enjoyment of the accent comes with psychological association.
Women have a tendency to sound better in that we annunciate our words more and do not stress the adjectives the way men do which causes the sentences to flow a bit more smoothly.
To someone who speaks a tonal language like japanese... in terms of pleasantness...
French
Italian
Spanish
Portugese
Greek
The rest of the smaller latin languages
some of the smaller european dialects of german which take in a stronger latin base
UK English
Australian English
American English
German
Scandanavian languages
Russian/russian dialects
They also get more difficult as you move down. Except that Norwegian, although scandanavian/germanic is supposedly more difficult to learn than russian if you are only learning how to speak.
