Deutsche Grammophon wants to make money just like everyone else.  They don't just give it away.

If you want some samples try here http://w3.rz-berlin.mpg.de/cmp/classmus.html or you can get tons of midi's here http://www.classicalarchives.com/#index.

If it will make you fell like less of a pirate go to your local library and copy or rip all the music you want.
