Could someone recommend a music file share program that is free and virus free. I have used limewire,?

But it has been outlawed, and when my computer crashed I lost all my songs. Before you tell me to stop being cheap, and to just go buy the songs let me explain that I am disabled and just flat don,t have the money. And besides that some of the songs were very old and are not in stores anymore. Please help me out if you can.
