Try posting a cover that you 1st posted on steemit (before any other social media platform or websites) and write a small story related that song(maybe when and how you sang it for your friend or family, can be any kind of personal story associated with that song) or a write up about why you like that particular song or maybe even both.
Also, Try using Italics and Bold letters to make your post more reader friendly.
