What is the most used accent in America?

I've been to America twice and they were both only for tour.

And I've never really lived there, but I like the American accent a lot and I would really love to pick it up.

And I'm also interested in various accents of America and in the differences among them.

Do you know such sites as somewhere I can listen to many accents and compare one accent with others?

And... Uh... I don't know you guys have ever seen the sitcom Friends but, Are the actors using New York Accent? I always thought they were using it, but my sister says it's all Californian...

I kind of fantasized New York accent, but it's kind of a bombshell(?) to me.

And is Californian similar to Midwestern?
And once again, what is the most common accent in America?

Thanks in advance.
