Read and write review for at least one other's lyrics!
Seriously, if you're interested to know what people think about your poetry, just put yourself on the other's place - there's a lot of beginner authors, and all of them crave for your opinion upon their lyrics - so give to them, and you'll be reviewed in reward. It's just like (it seems) our world works - if you want something to happen to you, do it first to some other.
