i have a 25 disc file-style cd player that doesn't work when it's put on "random". it eventually makes a clicking sound and and the screen shows, "no disc" the stereo is five or six years old and has never been cleaned. what should i do? also, i sometimes can't find song on burned discs unless you allow it to begin to play the first track, then search ahead. is there a program i should use to burn my cds that will minimize this?
