Hmmmm.... I dunno where to start with that really.
You say every 10 or so songs they had a hit. When they first started, pretty much every song they released went to Number 1 in the UK and then the US and rest of the world. By the time they finished, they had clocked up TWENTY SEVEN NUMBER 1 SINGLES. That is fucking ridiculous. Now think about this:
Love Me Do (Their First Single)was released in 62.
The Long and Winding Road (Their last single) was released in 70.
That is 8 years. 27 number 1's in 8 years is a fuck off feat for anyone.
They did things that the music world hadn't even dreamt of doing at the time. They invented feedback (well, they were the first to use it on Revolution), they invented the film clip, they changed the fuckin face of music as we know it. I STRONGLY disagree that Nights in White Satin and Paint it Black are better than any Beatles songs. But that is cool, that is opinion.
I'd argue that Lennon was as strong, if not a stronger song writer thatn Paul. Paul wrote sweet, pop songs most of the time (with many exceptions mind you) and John wrote the more experimental, cutting edge stuff. Then you throw in George who wrote some of the Beatles best songs (Something/While My Guitar Gently Weeps etc)...
I dunno.... I'm going nowhere with this post. Bottom line is, you're wrong
