DJEarWorm.com is giving away a free mash-up of 2009's best pop music songs, and you can get it for free, from their site.

First thing's first, what is a mash-up? A mash-up is two or more songs mixed together into one track. Usually, a mash up is the vocal track for one song mixed with the musical track for another song, and you can find a lot of these, made for fun, on the Internet.

This particular mash up is twenty-five songs mixed together, the best pop songs of the year. You'll find bits of hits like The Black Eyed Peas' “I Gotta Feeling”, Taylor Swift's “Love Story”, Flo Rida's “Right Round”, Jason Mraz's “I'm Yours”, Beyonce's “Single Ladies (Put A Ring On It), Kanye West's “Heartless”, The All-American Rejects' “Gives You Hell”, and Taylor Swift's “You Belong With Me”, among many, many more.

I know, it kind of sounds like it would be a mess, all these songs packed together, but I had a listen, and it's actually pretty good! Both the song, and the video, are available for free download at DJEarWorm.com, right now. Grab them both and check them out!
