guys i have the sony net md walkman mz-ne410. Apparantly I can't delete the tracks I have on my md because it says the songs r copyrighted. . I tried it with the switch in and out in the minidisc to make sure i didn't have it protected. Do you know how I can get this thing to delete the tracks. The tracks I have on my md are from my old computer so when i got a new pc and tried to delete the tracks it wouldn't let me . Please help I need new music when I go to work
