Reply to Burning CDs/DVD's

Hi guys, quick question / advice needed. I presently DJ solely via DVS (TSP). However, I am trying to get a gig here or there, and that means that at a minimum I am going to need CD's with my music on it in the case of emergency, or in the reasonably good chance that the venue only has older CDJ's that don't accept USB sticks, I will be forced to use CD's. My question is - how do you CD users prefer to burn your CD's? I am used to the vinyl concept of one song (or 2-3 I guess) per CD, but given the ability to hold numerous tracks on one CD, it's intriguing to put more than just a few on each in order to save time/space. However, I recognize that if you put too many on one CD, then you can't mix into any of the other songs on the CD.

So - how do you guys do it? Duplicate CD's to solve the problem? Only put a few songs on each CD, knowing that you will never be able to consecutively mix those together? Thanks for any advice/suggestions.
