How can I get free songs, to put on Blank CD?

Because I have GTA San Andreas, on Original XBOX, and I want to get songs on a Blank CD (Multiple Artists, Random) then Copy that to my System, then I can have GOOD Custom Soundtrack, And I Can't afford any CD's, And I want something with Good Quality, Virus-Free, Legal or Illegal, I just want songs, to put on a Blank Disc, I tried once with Media Player and it only got one song on the whole CD, So I want something on those guidlines, And I don't want Limewire services, because those mess the computer up. Thanks for all the answers.
