The RIAA has decided that, in its great wisdom, it disagrees
with you ripping your own CDs to your own iPod. RIAA and other copyright industry associations have previously submitted a report claiming that space-shifting and format-shifting do not count as noninfringing uses, and that this applies even when you are making copies of your own CDs.
"Nor does the fact that permission to make a copy in particular circumstances is often or even routinely granted, necessarily establish that the copying is a fair use when the copyright owner withholds that authorization. In this regard, the statement attributed to counsel for copyright owners in the MGM v. Grokster case is simply a statement about authorization, not about fair use."
