Copyright
The audio industry can be difficult to navigate at times, understanding the rights performers/composers/producers have in terms of royalties and intellectual property all falls under copyright, so it's incredibly important going into the industry to have at least an entry-level grasp on how copyright works.
Copyright is the ownership and commodification of intellectual property. It allows musicians, or anyone in general who comes up with an idea, the ability to make money off that idea, and receiving the proper compensation from people using your work. Around the world there are organisations setup to make sure artists of music are paid whenever their work is used. Whether it be by a Dj mixing one of your tunes into his set, or a radio station playing your song, APRA AMCOS is the Australian organisation that ensures the artists are paid their due royalties, and it really is a quick easy process to sign up. APRA handles the composition side of royalties, while AMCOS handles the Mechanical side, which is more performance based.
Focusing on the Assignments we've been given throughout this Tri, they have all touched on copyright in one way or another. Starting with the Electronic Remix. In the real world, when you do a remix of a song, you've created what is called in copyright law a "derivative work" and unless you've received permission from the owner of the original, you've committed an infringement (Sutcliffe,2016). Knowing that my artist is Australian, i would contact APRA AMCOS, who would be able to contact the original artist/performers to receive permission for the remix. After that we would negotiate the royalties distributed from the remix based on what stems/performances were used.
The soundalike is a bit of a different story, as if a song is published, we have the right to record as an audio recording, but not as a video. To legally record a cover song and post it to youtube you must receive whats called a Sync license, which gives you the authority to put your cover of someone else's work over images or video. However if you were to press Cds and sell copies of your cover song, you must 100% get the necessary Mechanical license and pay the proper royalties. Honestly when it comes to the Soundalike assessment we did, i'm still not 100% on the law because we covered the song and synced it with the original video, also from what i've seen from my research, action is rarely taken on a lot of the youtube infringements.
As for the Jingle, for me personally i used all samples that are covered by Creative Commons, which means that the uploader of the sample agreed that it can be used by anyone without any credit/royalties. Creative commons can cover a wide variety of copyright, depending on what kind of creative commons agreement the author of the content signs up for, e.g, you can upload your content for free but agree that people can only use it you are given named credit.
Youtube seems to have it's own algorithm for dealing with video content. Which seems to be fairly erratic, taking some videos down for copyright and not others. The world of Copyright seems very loose with its structure and laws, so my main recommendation would be to research anything you plan on doing which might infringe on the law.
