Study music

After many years of good services I am going to retire my current study music. Study music is what I put on when I study, it plays over and over again and the purpose of it is to fill in the background with something pleasant, not distracting, that reduces the distraction caused by random noise. I don't know how many times I have listened to Verdi's Nabucco but I have proved beyond any doubt that CDs just don't wear out no matter how many times you play them.
