I have never made an audio cd. I have copied some of my cds to my computer and played songs. My sister copied a cd for my kids and dropped it to my online storage drive and I in turn downloaded it. So, I have a folder with 20 separate songs in mp3 format. How do I make this into a music cd playable in most audio cd players? It would appear that the total minutes are around 73. Also, Is there a software that can analyze and convert and record/burn this if so I will buy it if I have to.
