I don’t mean to talk down to you, so forgive me if it seems like “mansplaining”. I have no idea of your experience level. I use my iPhone and just connect by blue tooth. I don’t know how you acquired your music, but in my music app, I can make up playlists. It also separates music by country/rock/etc. I use CarPlay and have about 4 playlists I jump around on and the infotainment center doesn’t seem to have an issue with it. My only weirdness is that it cuts out for just a second on the same part of my long driveway every time…not really so much an issue and a curiosity. If you acquired your music using something besides iTunes, which I suspect that’s what you’re saying, can you not download it into your phone library and use USB cord which makes the infotainment system mirror your iPhone?
