I think that most if not all of the Beatles music would be ignored if it came out today. If you watch a performance from the Beatles (I didn't say concert) like the Ed Sullivan performance (the concerts were more hysterical) there is a dignity and class. The music that is common or that sells is based on sex. The performers typically have a provocative costume on. The music is secondary.
If you are to take the performances out, and judge purely on the recordings another thing comes out. If you were to get many record producers/talent scouts/whatever you want to call them, to tell the honest truth, I think many would admit that it is about cashing in on the instant success of a performer. I know some of this was true with the Beatles as well, and that is the reason that 'A Hard Day's Night' was shot quickly and in black and white (cheap and instant). I think that this concept has been taken a step further than it was in 1963/4.
There was a lot of skepticism about The Beatles when they first appeared. If they had not of progressed they would not be the story that they are today. Whatever your time period that you prefer of The Beatles legacy, it is the whole that makes up the sum of what is considered greatness today.
There are other bands that had the success, or should I say could write as great of a song as Lennon/McCartney or Harrison. None, however, could do it consistently and repeatedly. If we only had 'Please Please Me' and say, 'Beatles For Sale', the Beatles would be a footnote, or would be just another band that a few liked.
The music industry will never see another Beatles because the music industry has closed the doors to this happening and changed the way a band becomes successful. They have even changed how the success is defined.
