Making unauthorized copies of copyrighted materials, not just music, is totally against the law. You will be subjected to civil and criminal liability – especially if you get caught!
It’s just that the implementation of our law enforcers is weak, so many are still not respecting copyrights and thus piracy still proliferates within and outside the Metro.
Supposedly, if you burn (duplicate) and distribute a copyrighted material, it should earn you a criminal record.
But, so far, there has been a very minimal number of violators getting caught and persecuted.
