Music and tunes are perhaps the most common files that would get the attention of being downloaded illegally to date. Copyrights of music coming from large recording companies and artists have obviously been violated by sharing files or having them burned to extra copies so that people do not have to go through the trouble of buying the actual album in music shops.
However, distinguishing and categorizing such issues has been something that has lacked the necessary declaration of when they are illegal and how they are considered illegal. People will just download anything they can find on the web.
Perhaps one thing that could help in putting a borderline would be to call the attention of people who are actually offering such files for download. On the other hand, a strict law outside that of such organizations as RIAA, must lay down the ground rules to have people more conscious of these illegalities. Lack of educational knowledge will render the whole endeavor useless and even if lawsuits would be files, there will be varying opinions due to lack of familiarization with such laws.
