Is it illegal if you take just one note? Here's a video remix made from samples no longer than 0.5 seconds from 107 different artists. Madonna won her court case over the use of a 0.23 second horn stab in "Vogue". Sabrina Setlur won her courtcase for unauthorized use of 2 seconds of Kraftwerk. So I have been wondering how long is too long when it comes to sampling. This video remix is to test out the algorithm. Will YouTube's copyright ID system take offence at Taylor Swifts voice appearing for 0.14 seconds and her face occupying 18% of the screen... Who knows?
