I started about a month back with the Gentle Beginner's Beats to get accustomed to it.
I've used the 8 Hour with success but this one has been the best for me.
I went and bought the download set of beats on the Fair Price deal that Jody offers
. 
My latest setup is using a Linux laptop with two media players.
One plays this Advanced 90  Minutes on a loop.
The other plays the soundtrack from a Relaxation Ambient Music video, again looped.
Mixed really low, just above the threshold of hearing, I had a 12 hour sleep just last night.
I'm finding the mix eases me into sleep better than the beats on their own.
That could just be me of course. 
YMMV
Nicely done! Thanks for sharing your experience, and thanks for the support! :)
