Sadly I do not have any advice to offer, but at the same point I would say if you can write songs like this it would be amazing. I actually catch myself humming this IRL and to my dog from time to time. Though I guess this might fall more under 'Singer' and to do the two together would be more of a 'Musical Artist.' Regardless, I need more catchy songs!
