Through the end of January 2011, Amazon is offering up classic rock albums for only $5.00 each in MP3 format. If you purchase MP3s through Amazon, it downloads into your iTunes account, so it’s as simple as purchasing directly through iTunes. Also, you can now gift these MP3 purchases – just click the “Give album OR song as gift” button on the right on the product page.

I’ve written about my love of Pink Floyd tons of times already, so I have to mention that one of the albums on sale for only $5.00 is Dark Side Of The Moon, so if you don’t already own this album, definitely grab it now, it’s insanely amazing.

Other albums available for $5.00 each are John Lennon‘s Power To The People – The Hits, which has 15 of Lennon’s solo hits like “Imagine,” “Instant Karma,” and “Woman”; Free‘s Fire And Water, singer Paul Rodgers’s first band and contains their hit “All Right Now,” and Styx‘s Crystal Ball.

I also want to point out that while it’s not a classic rock album, KISS guitar legend Ace Frehley’s most recent solo album — which is friggin’ awesome, by the way — Anomaly is also included in this sale.
