White supremacist and Neo Nazi rock music is flourishing worldwide.

According to the Southern Poverty Law Center, which tracks hate groups, music sales are a primary source of income for racist groups and a rich recruiting ground for new members.

The SPLC says the number of hate groups it monitors has exploded to over one thousand in the years since Barack Obama's election.
