I'm kind of a music connoisseur with thousands of tracks on my PC. You can imagine my disappointment when I discovered the sound system in my 2021 MY had no idea what a playlist was or how to use it. In my previous Grand Cherokee I could upload my numerous playlists to a thumb drive, jam it into the radio, and they played flawlessly. How is it a $60,000 rolling computer, running the latest technology, not know how to play music that is arranged in a simple playlist? Well I found a way around this that works pretty well at least until Tesla figures out how to make them work correctly. I use MediaMonkey on my Media Server to organize my music and create my playlists. I've also installed it on my Android Phone (should be the same on IOS). I upload my playlists to my phone along with the associated music files. Now connect the Tesla Infotainment center to your phone via bluetooth. Open MediaMonkey on your phone and select which playlist you want to hear and Viola it plays! I've been listening to my lists now for a few days and my Tesla is handling it pretty well. The music will stop when I quit driving and pick right back up where it left off when I get back behind the wheel. So far the only downfall is you have to select which playlist you want using the phone, but once it starts to play everything else is controlled on the touch screen or thumb wheel in your car.
