The limited-time deals vary depending on the company, and the discounted MP3s could be nice additions to your still fairly fresh cloud music services -- that is if you use Amazon Cloud Player, iTunes Match or Google Music.
In a promotion dubbed "Fuel Your Kindle Fire," Amazon is selling more than 1,000 albums for $5 each through January 2012. You can browse the choices by category such as country, rock, rap, pop and soundtracks.
Google Music, which on Cyber Monday slashed prices to $1.99 on popular albums, is back with a blowout sale on new and old products: $4.99 on more than half a million albums and $0.49 on more than 10 million singles.
Not to be left out, iTunes is promoting a $7.99 deal [iTunes link] for 2011's biggest albums -- including ones from Britney Spears, Coldplay, Foo Fighters and Foster the People -- as well as past year's hits, from the likes of Elton John, Jimmy Buffett and Neil Diamond.
