something wrong with my carplay recently. I have connected my phone to my car with bluetooth. But it doesn't work well. It makes my Apple Music keep pausing. So my friend told me that it is possible to
convert apple music to mp3 format and then save them on mp3 player. Using usb cable to play apple music in my car is not difficult. I tried it and downloaded one of the converters on google. TuneSolo helps me a lot. In the free-trial period of the converter, I converted my playlists from Apple Music.
