For the second time in the last ~3 or so months, I find myself sitting in my car, re-selecting favorite songs off of my USB drive, where I store a few thousand tracks, sorted in folders by Artist. Wondering if there is something peculiar that I'm doing or if others have encountered this as well. It's rather frustrating and a big time sink, as it takes me over an hour to go through all my mp3s and select favorites. My default listening behavior when not using FM or streaming audio is to jump into my favorites collection and just hit random. This is probably what I do for 75% of the time I'm in the car. To the best that I can gather, the Tesla media stuff doesn't leave any notion of playlists stored on the USB drive itself, so I don't believe that I'm in some way blowing that away when I add more music. The timing of this happening coinciding w/ firmware updates also strengthens my suspicion that it's stored somewhere in the car's memory and somehow lost as part of the upgrade. Wondering if I can mitigate by keeping locally stored mp3 playlists (.m3us) stored on the drive as well. Hoping someone else on this forum has encountered similar and has a viable workaround. Despite loving my car, the media experience is one area where my previous Audi trounces the Tesla quite handily.
