This post is going to focus on a peculiar nuance of the US intellectual property law that songwriters and producers should be aware of.
Obviously as this post is concerned with intellectual property copyright law it will only really be valid in the United States. More and more people are collaborating on music these days with the addition of easily swappable digital files. The problem is that when people come together to merge things that they have created into a new composition, those components are subsumed by the new composition. That is, they cannot be separated and used again for other new compositions as entirely separate creations.
