More info required as to what exactly you want to do. Are you saying that you want to transfer your CD collection to your tablet? Not something I would personally recommend as sound quality is usually pretty awful, although may be acceptable through earphones. Storage space may also be limited on this type of device. Make/model of tablet?
Or do you have a PC or laptop which you want to use as a music source? A more sensible proposition, but again sound quality may be an issue.
