Don't post lyrics here that aren't yours, like lyrics to your favorite songs.
Post song lyrics that you made yourself.
Also, post feedback on other people's lyrics! Tell them what you liked, what you think they could improve on/change, what really spoke to you...etc.

If anybody decides to SING their songs and/or have music to them...That'd be cool.

This might not stay: You can post songs that you sang [i.e. did a cover for] here as well, as long as you have a disclaimer somewhere that says that you're covering [Insert song title here] by [Insert artist name here].
