it's not music in this case. it's child *advertiser censored*, probably gore *advertiser censored*, probably with abuse of children involved. so I'd say, yah, there should have been more parental responsibility and oversight.
kids these days - they should have more supervision obviously.
they shouldn't be walking alone when there's a predator on the loose, and kids shouldn't be so messed up and so free to be predators in the first place.
Oh... I think it's all one big ol ball of wax.
