hi anf welcome to the site. The aim of the site is to encourage constructive critique... ie the process should be Observe, Analyse, Suggest and Discuss. After all if there is an issue, as writers it is better to know than not, and to know what works and what doesnt. At least you can then follow (or not) any suggestions, knowing why you were swayed to make a change.
The point is, critiques are opinions, not an absolute ruling, no matter who makes comment. Like all writers going through the process, you will find some fellow writers whose word you trust regarding getting your songs to where you want them to be, and others whose comments, though interesting or useful, take your songs in a direction you want to go.
Please, dont take critique personally. It is a specific song being analysed, not you. If you get a comment, really try to understand the point being made, and the perspective it comes from. Often they have a very valid point. If you truly try to understand point and perspective it makes a huge difference to the amount of benefit you get from critique. With each song, learn, improve and apply what you learn in futute writing.
Just my two cents.
