Anyone know of a safe place where I can download and burn music legally for free?
There's really no such thing. If you're legally downloading copyrighted material, then you're paying for it. If you're not paying for it, then it's not legal. Unless it states otherwise.
As for Limewire, yeah...that bugger's full of malicious stuff just waiting to rape your hard drive. Also, downloading music off Limewire is illegal. And even if it wasn't, it should be cause Limewire is evil! hehe
