Under Section 107 of the Copyright Act of
1976 allowance is made for "fair use" for
purposes such as criticism, comment, news
reporting, teaching, scholarship and research.
Fair use is permitted by copyright statute that
might otherwise be infringing. Non-profit,
educational or personal use tips the balance
in favor of fair use.
The usage here is also in accordance with
the UMG/YouTube Agreement, as full
credits/links are provided to YouTube and
any other source. The purpose of this
collection is to preserve the best songs
forever and to drive sales through
Amazon.com, which again benefits all
parties. Otherwise everything is offered
free of charge.
