A Publihser is correct on one point only, anything copyright properly established IS PROTECTED from unauthorised copying of any kind!

Means that when you 'print' cr stuff off the internet you are breaking the law. There are some exceptions here which are conveniently ignored by Music Corp et al.

1
The material was STOLEN in the first place, VERY VERY VERY common and easily demonstrated! 2
Lyrics that give the appearance of being original are often composed of snippets of existing cr or pd material, hence not created more like rearranged rhymes.

Exceptions
Public Domain songs. Happily there are thousands of mostly folk PD songs. Some of these are reworked by copyright people BUT you can still legaly sing, play, record em.

Some previously cr songs are now pd so they too are exempt.

Conclusion.
Like it or not what Music Corp is protecting here was ripped off in the first place with a few exceptions! Thus it is not MORALY WRONG to copy this stuff if you can get away with it! It ought therefore also to be legal so to do, but as Politics and Money are the criteria the bullies win and you the public loose.
