This document discusses a proposed music streaming phone case that would allow users to access high-quality personalized music playlists without using mobile data or requiring constant internet access. The case would download music playlists over WiFi to be cached and streamed from the case via Bluetooth when on the go. It would learn users' music preferences based on what they listen to or skip and the time of day. The music streaming case could connect to other devices or headphones and would be available as an app for download on Apple and Android devices for a small monthly or yearly fee.
