Darrell Scott wrote the song after he moved to Nashville ("Music City") so I guess it's a bit of his own situation: young family moving to Nashville, risking it all, starting anew, probably with music ("You take your number and you stand in line/And they watch to see how high you're gonna climb/Pat on the back 'n' better luck next time") and it seems that they fail. So for them the big chance was a disappointment.
