The mind is always trying to place order onto the world and grouping seemingly "like things" is a natural process. However, I do think the Music Industry and it's "FAITHFUL B*TCH", the Media, are forever CLONING POPULAR SUCCESSFUL ACTS. see --->

The Beatles = 1 Direction
Madonna = Lady Gaga
Gwen Stafoni - Avril Levin (sp?)
Michael Jackson = Justine TimberLACK, Usher Raymond
TuPac = Ja Rule
Shania Twain = TRAILER Swift minus the talent & beauty
Amy Winehouse = Adele
Lil Kim = Nicki Minaj
Justine TimberFAKE = Justin Babble
Robert Redford = Brad Pitt

.....and so on!!
