I am running Sonoma on my iMac. I wanted to copy music from a bunch of cd's I have onto a flash drive so I can listen while driving. I searched for help in a number of different places and cannot find the directions I need to accomplish the task. Most of the help I encountered was very dated or they want you to buy a program to do what I want. I can load the tunes in Apple Music and convert them into mp3 but I can't move them from the Music list to the flash drive. Any adivice would be most appreciated. Very frustrating . Also, drag and drop doesn't work for me with the tunes.
