I love Nashville. I listen to the soundtracks a lot on Spotify. I didn't realise I liked country music until I watched Nashville
My predictions (I don't know spoilers. Nashville and game of thrones are the on,y shows I don't look up spoilers)
jeff dies - lots of plots can come from that - re juliette and Layla (I liked him and Layla, I thought they made a good team)
Marcus - becomes a bit obsessed by Rayna. He's got devilish eyes and he's flakey. I think there needs to be something that rocks the boat with her and Deacon and I can't see her falling for Marcus after her life long live for Deacon.
(Marcus reminds me of a cross between Jonathon Reece Myers and Bradley Walsh 
On the fence about Scarlett and gunner. I love their music but not sure if I want them to be together.
I so want Jukiette and Avery to get together and BE HAPPY. He is so good for her but she just has the self destruction gene. I like the 1st season where they explored the relationship with her mum. I reckon the Jeff incident might be a wake up call. I wonder if Luke's son seeing what happened serves both to NOT have a long investigation to see if Julieete pushed him and also as a way of him going off the rails and dragging Maddie with him. And i think she'll be pregnant too.
Sorry for the ramble. I know no one, other than DH, who watches Nashville.
