The critically acclaimed World of Goo (PC / WiiWare), has certainly captured the hearts of gamer's this year. 

Kyle Gabler (the guy behind the music of World of Goo),  is looking to spread some more love with the availability of a free World of Goo soundtrack download via his web site:

Thank you to everyone who emailed asking about a World of Goo Soundtrack. This is probably as close to an "official" soundtrack I'll ever make for the game World of Goo. I'm making it available here on my personal portfolio for free. I wrote much of this music specifically for the game, but many of the tracks were excerpts from music I had written previously for various small projects, or just for fun. This soundtrack includes the full versions of most of those songs, as best as I was able to recover them. Notes accompany the tracks below.
