These Youtube videos are my favorite audio tracks I listen to when meditating. I find the binaural track’s music and nature noises help give me something to focus on, in addition to my breathing and occasional mantra. The binaural beats themselves help me get me to a meditative state quicker than if I didn’t use them. Remember you need to use headphones for the binaural beats to work. I also wrote some thoughts on getting into meditation and what binaural audio are if you are new to either here.
Here are a few I listen to regularly:

I hope these help in your quest for a quiet mind and present state.
