To copy your own CDs (back up or otherwise) I'd recommend
EAC (Exact Audio Copy). It's freeware and it is quite simply the best. Not necessarily the fastest, but the best for digital audio extraction.
Now if what you really want to do is download music, then just say you want to download music. I'm sure we can offer help in that area too but I don't think many are keen on trying to decipher unclear or intentionally vague messages.
