How can I tell if a song is copyrighted?
Copyright protection is available to both published and unpublished works. That means that the copyright for any work, including a song, belongs to the author who created the work. Only the author - or those who the author has given rights to - owns the copyright. This generally means only the artist and his/her record label, and the songwriter and his/her music publisher, have copyrights in and to a given recording or song, respectively.
When we buy CDs, we do not own the copyrights to that music just because we purchased the album or single. When we purchase music, we only own the right to the particular copy that we acquired (i.e., we do not automatically have the right to make copies of the CD or to perform the CD in public places such as in a bar, retail store, dance club, etc.).
The symbol "©" (the letter C in a circle), or the word "Copyright," or the abbreviation "Copr" will usually appear with copyrighted materials. For example, if you look on the back of a music CD, toward the bottom of the small print you will find the symbol "©" to designate it is copyrighted and who holds the copyright on that album. Despite the fact that online music files don't have the copyright symbol present in such a visible manner, you should still assume most music online is copyright protected, just to be safe - in fact, most legitimately acquired files do have copyright notices embedded in the data, such that they may be displayed via your digital music player.
