Free music downloads site in the internet

When I see a good free music site in the internet especially if it holds the songs I really like, I am actually in seventh heaven. You see I am a hardcore music lover and I have such a large collection of music of generations and all genre that I have built through years of downloading and saving in my computer and still there are more to add up especially if there are new good ones or even rare versions of the songs I like. Of course that is possible only through free music downloads sites out there and I could say there are also times when I am having a hard time finding a song due to its rarity. It was even funny at times because it turns out even free Christmas music downloads can be the hardest ones to find so when I discovered one such good site like carangel.com, it is already stored in my computers database.
