In what looks like the biggest music sale since the new and improved Google Music linked up with the Android Market back in November, millions of individual songs and hundreds of thousands of full albums are being offered for discounted prices.

Over at the Android Market, we’re notified that this is of course a limited time offer, but how limited is yet to be determined.

We’re proud to offer you over half a million albums for $4.99 and over ten million tracks for 49¢. Search around the site for your favorites—we promise you’ll find something you like at a great price! Few things in life are more important than music, and, since we launched the music store in the Android Market a few weeks ago, we’ve sought to connect you with the tunes you love.

* Promotion excludes single albums with original retail price above $15, double-albums, and tracks with original retail price above $1.29. Google Music artist hub and Sony albums and tracks are also not included.

Unlike another recent Google Music promotion that discounted holiday songs, this sale looks to feature music from all over the place. The front page selection of $0.49 tracks features varied artists like Nirvana, Radiohead, Drake, Rihanna, Stevie Wonder, and M83.

The full albums that Google is offering for $4.99 include older classics like The Police’s Synchronicity as well as new hits like Coldplay’s Mylo Xyloto and Kanye and Jay-Z’s Watch The Throne.

So head on over and stock up for the winter. If anything will beat back the mid-January blues, it’s got to be a bunch of new music.
