all my music, orginal cds stay clean as fuck cuz i copy em to the computer and store em away....there hundred percent scratch free, and i just burn cds as i need them from my comp. But storin in cases with cloth backs is better cuz u aint gonnna take it in and out the cases, just slide it out. In my car, i just dump all the cds in my middle console, sucks if u have to stop on a dime n all them go crashin inward.
