Sure, you can post songs. Just be aware that anything you post you risk losing control of. So if they are songs you would actually like to have produced some time and make money from, you probably don't want to be posting them in a public fora - here or anywhere. Not to discourage you from posting, just want you to be aware of the situation. You would technically still own the copyright.
