I've been listening to binaural beats now for a long time. I listen just about every single night... i have a really good one that's lucid dream guide (i've gone from never remembering my dreams to having crazy dreams every night, but i'm can't get lucid, except it has happened a couple times, so that's progress for sure.

It's from Brainwave Mind Voyages. They have a whole series of guides for different things. SoundMind is excellent as well.
