Smirk,
There are probably millions that surf mp3.com
Get your songs to "radio stations" on mp3.com and start your own "radio station". The deal usually is...hey host my songs and I will host yours...
Yes the copyright office has a site.

Like Mr BB Jones said. A good promotion for a working band.
Use all media that is free and link your website from there.
Bait with the freebies and they will come.
If you can't wait for the copyright office to drag the application though the perverbial government red tape.
To cover thy copyrights tail, mail your work to yourself.
That way its postmarked (make sure that its legible) to prove that the work is yours on that date. Include in the mailing,lyrics,score or tab,if you have made one, tape or cd, and an copy of your copyright application(s). Leave it sealed, just in case its pirated without your permission.
Always tag any work your put out "copyrights pending".
If you do a remake, give the credit to the person who wrote the song. If you put it on a cd for resale you will need their permission, and the lawyer dance will begin.
