okay lets say the lyrics are copyrighted

the music is not...

essentially we still cant do shit with the complete songs right?

Wrong. Once you complete the song (with only your material) you can copyright the MUSIC OR do a Sound Recording Copyright (FORM SR) OR you can do another PA and write in your PA Registration # indicating that the lyrics were previously copyrighted. When that happens you will need a FORM PA - not the short form.

what can we do with this half copyrightten material?

It's not half copyrighted. Your lyrics would be a full copyright of their own. This will prevent theft and prove creation date.

i think if we send in a disc it will be cool.. i dunno i may type it all up.. if i do type them do i need to trancribe the entire song verbatim? like adlibs and shit too?

You would need to transcribe verbatim adlibs and all. If you want to send a disc - that's fine. And if there is anything MELODIC that is copyrighted along with the lyrics. In that case, if it's not just rhymes, send a disc. And then your melody AND lyrics are set.

:) Hope I'm helping!
