As an aspiring musician, I would have zero problem with my music being pirated. Why? Because I'm out to transform music, whereas 99% of artists across all of the "big money" genres just want to get rich(and therefore just copy the style of whoever they perceive to be cool). Rap is by far the worst offending genre, as soon as anybody gets a record deal, their next 60 singles go something like: "Uh, yeah, I has money, gold-plated grill, da lambo in da garage.... etc...."
I'd rather have my vision of music played far and wide than to become rich off of it.
