[quote=""'[R-COM"]Hauteclocque;1253523']If the songs are enough old, you have the right to use them, I don't remember how many years it is.
Imagine that the Beattles will be free of rights in few years...

It's 70 years after the author dies in most places, as far as I know. But it varies from one country to another. So, it might take a while for the Beatles' material to become free of rights!
[quote="cagumelo""]Yeah i thoght about the copyright before, but are 2 songs that I like and are realy brasilian, but like I said no one has never used anything like that on PR.
anyway, I have a group its not that big deal but we make a good sound, we could do some songs and show you guys, as it is not high priority i can talk with then and give an answer to you later. I have very good musical taste not those emo songs that they sing today so don't worry.[/quote]
What exactly is "very good musical taste"? As you said, yourself, it's a matter of taste; something "very good" to you could be something awful to someone else. Why not keep it neutral as it's always been in PR and have the traditional - but awesome - suspenseful action, movie-based themes?
I, for one, love the soundtrack for Project Reality. It's really inspiring to play after listening to those loading songs. Well, my point is: we already have music providers and the music the Devs want, I suppose, are all standardized. This is probably one of the lowest things in the list of priorities and I don't actually believe it's necessary, or even possible for this faction to make it's own music into the game.
But, hey, that's me. Maybe someone else would agree with the idea.
