What are your feelings on this, do you agree or disagree?

The saying "it is what it is" and the song "Let it be" by the Beatles are pretty much the same idea? The saying "it is what it is" basically means even though the situation isn't exactly what you want, it's pretty much unchangeable and you might as well just accept it and move it.
I feel the song "Let it be" kind of conveys the same message. Even though things aren't what you what them to be ("when I find myself in times of trouble") sometimes it's best to just accept them and move on ("mother Mary comes to me, speaking words of wisdom, Let it be")
Maybe I'm wrong, I don't know. It just seems like they're both making the same point.
And when I hear people say they don't like the saying "it is what it is" I wonder how they feel about that song lol
