Sometimes after launch no song is selected and the back/play/forward buttons are disabled.
But other times the top track is selected and the buttons are active, clicking the play button while in the music library, with shuffle mode active, only one song plays and after that playback is stopped. It works if you play any other song but the one a the top (the one selected as default).

[_LOG_LEVEL_FATAL 20:10:56.031204] noise_playback_manager_playMedia: assertion `m != NULL' failed
[_LOG_LEVEL_FATAL 20:10:56.031327] Music will not function properly.
[_LOG_LEVEL_DEBUG 20:10:56.033850] LibraryWindow.vala:1045: playback stopped
I experience this too so confirming
Also from duplicate report:
"I have to select a song for shuffle to work. Also on reboot, it won't go to the next song unless I select another song."
