Welcome back!
The lyric brought forth the expression from the old real country days, i.e., "true life blues."
The work that went into your production is indeed impressive!
Over the last couple of years here on the forum we have listened in amazement as the use of synth vocals has become exponentially better and better and Suno has taken it to yet another level.
And On Blue Highways is an excellent example of that level.
Okay, you tried out the Dark Side

but as you likely expected us to say, we miss your vocals!
Great to see and hear you and best to you - especially to the thumb.
