I've had two cars with playlists-on-USB that treat the files very differently. My Infiniti treated a folder of music as a playlist, while my wife's BMW requires a playlist file (can't remember the extension, but could export from iTunes). Does anyone know how a Tesla recognizes playlist files? I searched Google, and these forums, but couldn't find any thread regarding playlists. Forgive me if this has already been discussed, and if so please point me to the right thread. I'd like to plan ahead, and have it ready when my car is finally delivered. Thank you!
