Well considering the Beatles are the best selling music act of all time I think they're in the same "league". The same goes for Elvis.
Now according to wikipedia (I know it isn't gospel but it sure is convenient :P) It goes like this.
1 billion +
Beatles, Elvis
500 to 999 million
MJ, Crosby
That doesn't even take into account the Beatles solo sales either. So the Beatles are definitely in the sale league.
