Need help down grading my tech

I need to find an MP3 device that can take spotify and audible, it must have bluetooth and wifi but be able to use Audible and Spotify offline. A display isnt necessary and i dont care if it runs Android, IOS or Windows or something completely different. As long as I can enjoy my music and audio books without illegally downloading it, by cracking the DRM protectes files. 😊 The idea is to down grade my phone to a Nokia 3310 and have this on the side, so i dont have to carry around a giant screen containing SO-ME in my pocket. Please help me, and if this post isnt allowed then please help me find another subreddit where i can ask 🙂 via /r/tech http://bit.ly/2wxaMV2
