Best way(s) to listen to REI audio books

[Brandon Neuberger]

Hey all! I'm brand new here and looking to learn as much as possible. Speaking of learning, I'm not yet involved in my first deal but I am learning from a mentor (much more heavily come November) and reading as much as possible. Despite not yet having a deal, I'm attempting to leverage my time as much as possible by reading at home and listening to whatever I can while at work, commuting, and even showering.

What are your favorite ways/apps to listen to real estate literature (bonus points for anything from BP publishing)? What do you find has the widest selection and give you the most value for your money?
