You need to extract files from your CD and copy them on your cellphone.
For extracting, I personally use Asunder, which is available in Lubuntu repository and pretty simple to use.
For copy, you'll need to connect your phone to your computer with Bluetooth or USB cable.
Here's what I did to get it working:
sudo apt install sound-juicer
sudo apt install lubuntu-restricted-extras
