If mixing of cdj’s ill burn 2 mp3 cd’s the same, then you can mix 2 of the same songs together and you don’t have to worry about not being able to put 2 tunes together. The display give you the song names so your away. Just like searching through a crate. I usually arrange the tunes in some sort of order E.g, more chilling stuff at the start, harder stuff at the end!

If your on cd decks that don’t display the names then 4 to a cd max deffo
