Describe the bug
If there is only one song available in the "Currently playing" drop-down of the music options, it will fail to continue playing music after this song is finished.

This is especially problematic in the years such as 1938 and 1939, where with "Play only music for current era" selected, "Flying High" is apparently the only option. Thus, if you are playing the game normally with the in-game music enabled (and do not reset the music by pausing and resuming the game), the game will become eerily silent until 1940 rolls around.

The music stays silent even if you toggle "Play Music" (under the ear button) off and on.

This doesn't appear to happen in the original Locomotion: the single music track appears to loop instead of stalling, in the Steam version.

To Reproduce
Steps to reproduce the behaviour:

1. Be in 1938 or 1939 and have "Play only music for current era" selected.
2. Wait for the song "Flying High" to finish playing.

Note that there will no longer be any music playing, despite the UI indicating that music should be playing (screenshot bellow).

Expected behaviour
I would have expected "Flying High" to loop. (The original Locomotion behaviour appears to be that).
