The Beatles have their place in music history but in terms of actual talent and vocal quality, they don't even come close to the Motown groups of the 60's and the artists of the 50's......
These types of lists are useless since everyone who reads them have their own personal preferences..........
The Beatles were a “complete” package (plus producer).
The Motown acts were pre-fab, put together a singer with a backup singing group, with a songwriting team, with session musicians to play the music.
