I'm having issue with my weekly discover on car Bluetooth

[#1]

While playing my weekly discover on my car over blutooth the playlist plays part of it, like if it have less music on then. It play something like 4-5 musics then it stop the same way when it finishes the playlist. If I press play on the car it start over the same 4-5 musics, but if it press to go to the next song it continue the playlist, but after a few musics it stops again the same way as told above...
