So I'm making a playlist of my favorite songs for a road trip, I dug up an old CD that is re-writable(hence, the RW in the question ) Its an old sony brand CD-RW from 2004(old, i know) It says it can hold up to 700 MB of data or 80 min of music. I read online that 700 mb is the most a CD can support, so i was wondering if i could burn mp3's onto this old disk and be able to play them in my car CD player. Does anyone know if i can, and why or why not?
