Just a quick one Niteshift

Yes when the song is in Public Domain , you can record
it with your own arrangement and collect the royalty

It's only a typo Niteshift but the word as I am sure
you will know is Copyrighted not how you spelt it
protects the Rights of the Composers and Owners,

I mentioned it because i have seen this error
many times but just the once on here

Copyright law in other country's vary on whatever
particular country the song was originally
protected

In that respect, song components are either enhancing or compromising their combined effects.
