In theory, RIAA means Recording Industry Association of America.
In reality, the RIAA is an organization who have ripped off its membership and we consumers for decades. The RIAA are a bunch of fascists who will not embrace the digital market, and would rather force everybody into paying high, overpriced markups on a CD or a single song on an album...from 1975...that's barely in print. And even if they do embrace legal digital downloads, they won't give out the full category of music, then they want to jack prices up for downloading the music that is available to continue thier racket and profiteering scheme.
They don't give a damn about the people buying the music, much less the ones making the music. To acheved that end, they will threaten to sue you for $750 on one song, then try to make you settle, and still walk away with more cash in their pocket, rather than distrubuting cash to the songwriter, artist, band, or whomever had a hand in the actual creative process. In short, RIAA really means Rich Indignant Assholes of America (That Happen to Work in the Music Industry), and they are the cancer on the very industry they claim to protect. The greedy-ass motherfuckers.
The RIAA can take their $25 CD's, $8 Singles and their desire to raise prices on iTunes, and shove it up their ass. Fuck 'em.
