I fail to see a problem with this.
First of all it's an insane decision to retroactively extend the copyright..
This is just something that will benefit greedy record labels..
If something is public domain, it's public domain..
Imagine having used material from public domain songs, and suddenly you have to pay for your own creation.. and have to recall it, if you're selling it..
I don't know if they demand payment, since it's retroactive..
Wouldn't it be fun to have just printed 10 000 copies of your album that has a public domain song on it, that's suddenly copyrighted?
It feels like going to a supermarket and they're having a chef there to give out free samples of a product..
-Here have a sample of our chocolate cookies!
-Thanks, it tastes good!
-Now I need money, it was free a moment ago, but we now want money!
This is only for the big labels that still want to cash in on The Beatles, Elvis, etc..
