Hi paddymad, congratulations on the new tablet and welcome to the forum. I'm moving your thread to the Android Tablet Q&A section for you, where more people are likely to join the discussion and try to help you get those CD's onto the tablet. Good luck!
Further to icbi24, I'm assuming your CD's aren't even in MP3 format yet, if not you need to "rip" or convert the CD's to MP3 format. There are NUMEROUS free programs that will do this for you. After you have done that, you can simply copy the MP3's to the tablet. To play the MP3's there are again NUMEROUS apps that you can choose, both free and paid. You can google "rip cd to mp3" for instructions on converting the CD's.
