Why is my MP3 song created in Logic Pro not playing on Apple Music via CarPlay?

I cannot play an MP3 song, created and bounced by myself via Logic Pro on MAC, via Apple Music in my car (using CarPlay). The system will fail when I try doing this. What is the problem here? It worked well in previous software versions.

First step: I create a new song in Logic Pro

2nd step: I bounce the song to get a MP3 file which I upload to my Apple Music Media cloud database.

3rd step: I connect my iPhone with my car (using CarPlay)

4th step: I select on the car's screen my MP3 song in Apple Music

After these steps the song will not play. Each time I try doing it, the system will fail.
