I had two totally different experiences. With the birth of my oldest almost 6 years ago, I used the Mongan Hypnobirthing program. My instructor also made us a CD with her reading a bunch of different tracks (like glove anesthesia, etc.) in her home recording studio, so I had a lot more variety (more like Hypnobabies).
I had a relatively short labor for a first timer (a little over 6 hours). I pretty much listened to my CDs non stop and was in a zone that way.
With my DD, I used the Hypnobabies supplementary course (and my Hypnobirthing CDs, etc. as well). I think I listened to them a bit at home. Most of my labor I wasn't sure I was even in active labor. I was only at the birth center for about an hour, and during that time I had NO interest in using my CDs. I just used my breathing and relaxed and felt very calm without them.
This time around (baby #3) I have no idea what I'll want, so I'll have my hypnosis stuff available and I also made some different playlists (calm/relaxing stuff, more upbeat stuff, and then some just instrumental/new agey kind of music) just in case. I like having options
