how can i do for cda

[CincoBoa]

I have a one of a kind track that I can't replace that was in .mp3 format. But now it's in .cda and I can't for the life of me figure out how to get it converted back. It's the standard 44 bytes that every .cda shows as, it's in my file explorer but I can't find a file converter that will recognize it. It won't play with iTunes or Windows Media but it will play with VLC Media Player. If there are any suggestions I'd love to hear them.
