Without meaning to sound facetious the most inexpensive way to obtain copyright protection in the US is to do nothing.
It isn't necessary to take any action to obtain a copyright. Copyright protection is automatic, as soon as work of sufficient originality is "fixed in a tangible medium, perceptible to human eye, machine reader or other device".
In the US, though it is true that a copyright is automatic when the work is fixed in a tangible state, in order to bring an infringement suit to court your copyright must be registered with the copyright office (www.copyright.gov).
Some say that you can secure a "poor man's copyright" by putting a copy of your finished work in an envelope, mailing it to yourself, and leaving it sealed, (therefore "proving" that you created the work on or before the date it was mailed). However this does not hold up in court either.
So, the cheapest way to copyright music in the US is to go to www.copyright.gov, decide whether you want to use Form PA (to copyright the "idea" of the song,) or Form SR (to copyright the actual recording of the song,) and register it electronically. I believe it's $35 per work. May seem expensive if you have a lot of music, but think how worth it copyrighting your stuff could be... if someone steals your stuff and you can't prove that you made it before they did, you'll be very upset with yourself.
An original song is automatically protected by copyright as soon as it is fixed in a tangible medium (notated or recorded).
Legally nowhere due to copyright law.
Yes, You can CopyRight a domain name for Free.... Just type "CopyRight a Name for Free" at the top of the page.... Choose wisely!
That would be copyright infringement if the original song was protected.
You can only copyright a song if you are the song's author. You can't copyright someone else's song. Although the author can sell you their copyright.
You can't patent a song or poem, but you can copyright them to protect your original work. Copyright is automatically granted once the work is fixed in a tangible form (written down or recorded). Registering your copyright with the appropriate government agency can provide more legal protection in case of infringement.
Each song has its own copyright year.
Using copyright-free materials is much cheaper and easier than negotiating for a license with the copyright holder of a protected work.
When you directly quote what someone else has written without their written consent. When you offer free downloading of a popular song that was just released or is still in copyright (95 years in most cases).
It is probably copyright infringement. There are exceptions, though.
The only way to be certain is to contact the copyright holder yourself.
Free of copyright restrictions (generally speaking).
No. If you buy a recording, you only have the right to listen to it yourself, in private. Anything else requires additional permission.
