Check out this quirky video by Dean Fields. The tune is easy to the ears and very catchy. You warm up to his voice right away. If most of his songs are like this, then I am sure he will definitely get more stumblers. There are nice passages in the song composed of keys. I think the equation of success in music is simple. Just make sure you have a good voice. Also, you make good songs that people can hum along to. For me, keeping those things in mind will get you somewhere.
