If the song is too short for you, then put it on repeat.
Confession: I’ve never played this song for any of my games, nor have used music from the rest of the Firefly Soundtrack.
Why? I just don’t run westerns/or space westerns. Also, most of the tracks are too short for my tastes, with lots of changes in pitch and tempo. I prefer more ambient music.
But there is good music here worth listening to.
