You will need a PC with a CD drive (it can be external), loaded with ripping software such as dBPowerAmp Ripper or JRiver Media Center. Run the ripping software and set the location of your music library (which can be a networked drive). Load the disc, wait while it is read. You may need to help the software identify the disc so that the metadata or artwork is picked up correctly. Select “Rip disc” and wait until the process is complete. If necessary, edit the tags and find the album art on the internet. Eject the disc. Job done!
