No Rap for Gangs

Dutch authorities are playing loud and annoying Christmas carols in public areas to keep teenage gangs off the streets.

Charlois Council in Rotterdam have started blasting out the Dutch children's carols from a barrel organ at the Zuidplein underground station. . . .

A council spokesman said all the unruly teenagers had disappeared within a few minutes of the carols blaring out.

If certain music causes gang members to leave, might it follow that certain music attracts gang members? If so, what kind of music? I'll leave that to the reader's speculation.
