DJ help!!

We're going next week to meet with the dj company that we booked last year..I asked if we'd be meeting the dj that will be doing our wedding, and the woman said -no, we'd be meeting with her, the djs dont come to the office.
How will I know that certain songs we've requested will be played? Did anyone else have a problem with this? I want to make sure that especially for our dances and the bridal party entrance and everything that the songs we've chosen are what will be played?

I'm sure if you fill out a sheet of specific songs to be played then don't worry about it. I'm sure if you want to meet with the DJ maybe you can meet with them when the wedding gets closer. If they do that all the time then tell the woman that you're concerned that the specific songs you want played will be played. Good Luck
