There is an interview out with Carol King. A comment is made that many of the songs of the 50's and 60's all sounded the same. Songs like Under the Boardwalk, Up on the Roof, and dozens more of that era, were the same writers all writing in the same rooms in the Brill building.

Motown had a dozen musicians that played on over 300 number one records. The "Wrecking Crew" was the LA outfit that played on almost every hit record coming out of the 60's, 70's and 80's in rock and pop.

The nature of the music industry is that you create a community, use the people who are successful and do it over and over again.

If you are a business like Apple, GE, Facebook, Google, you don't constantly monkey with the formula. You use the things that work and make them work over and over.

So they all sound the same eh? That pretty much makes me laugh. a few songs people hear on the top of the charts might sound similar, but if you think that, you are not listening very hard.
