I post lyrics for my own songs only on my website.

I do not post lyrics or charts for songs to which I do not own copyrights. I believe you will be in breach of rights to copy laws if you post them - technically speaking you are publishing them when you make them available on your website.

Now - I know a lot of people do - and I know there are battles (with Harry Fox and probably others) over this. I suspect you'd find sympathy from many of the songwriters for posting them and maybe even get their permission, simply by asking ...

BUT I believe you'll find that you must pay a license fee and/or have the author's permission to post lyrics and/or charts for other people's music.
