Websites have access to the entire world repository of music that can scan an upload against like 75,000,000,000 different files and movies and content in almost the fraction of a second -see they have the matrix all in order their focus is on controlling humanity now they will police all realms of creativity they know things like art and music are highly suspect in altering people forever so they want to copyright everything so nobody ever builds on creativity it is just held by a few actors and the rest of us never had the courage to be the queer resistance for example :) and challenge art cause I know this of my male art I take images that are suspected copyrights and alter them 97% and create my own art piece so this is very theoretical in the case of my blogs I ripped 2,500,000 pics of about 1000 blawgs to form the content for 3 of my blogs so nobody would have the time to go down this road -they are too scared of infringement but if you understood how the law works there is certain protocol people have to prove they sent you a cease order and you ignored it therefore rendering a potential lawsuit but they just cant right out right sue you and if they do for art or music you will most likely be approached by a pretty high echelon celebrity attorney pro bono anyway its funny nobody has the courage to go into uncharted waters when it is those waters than may bring you your fame, or infamy so to speak
