As for the song publishing aspect, I’m not sure how to make that happen. The traditional route is to move to Nashville, sleep in your car, get a publishing deal so you can write every day while also working as a bartender, then Hope something eventually happens for you with the publisher
I’m unfortunately way past the point in life that I can give up my day job and move to Nashville for a $30k/yr publishing deal.
So, beyond someone somewhere doing me a favor and sending a copy to Kenny Chesney or whatever, I don’t see a great avenue for me to “make it” as a songwriter or artist.
But nothing could ever happen without first spending the resources to get these songs recorded
Bank in the late 90s we went to a bar in Daytona with two good friends to see an artist they knew, small gig but he had recorded a song from a writer who also wrote songs for Garth Brooks. Her name is Victoria Shaw. She sat at our table with our friends. She wasn't chatty at first but after a few drinks my wife asked her how she started writing songs for people like Garth Brooks. She said she spent years playing bars in Nashville and it is common for bigger acts to come listen to sets and see if there are songs they like. Then after some people started recording her songs she started getting together with other song writers and writing together. She also had her own band. Just someone we spent a few hour with. I don’t think we have ever heard her music that she recorded.
