My Question or Issue

 Found this pretty niche UI bug, not sure exactly which of the steps below are required but I'm not able to narrow it down anymore on my phone.

Repro:

 - Add a song with the 'new' play UI (not sure what this is called, but it seems more themed? I saw this with the song 'Sweet but Psycho') to a playlist.

 - From the playlist, play this song.

 - Turn shuffle on (also will repro if shuffle is already on).

Expected: Can press 'previous' to go back to the beginning of the song

Actual: The 'previous' button is disabled, so I can't go back to the beginning of the song.

This isn't an issue with other songs, so seems like it's related to the UI used for this song (and other new songs) specifically?
