Electronic Arts on Thursday began offering soundtracks to its video games on iTunes, but it took a unique approach: instead of actually publishing albums, the company simply created iMixes that link to the already-existing songs on Apple's music download service.

EA says the offer, dubbed EA Trax, comes in response to customer demand for the music it embeds in its games, which ranges from popular rap and pop to obscure indie rock. The game maker says 55 percent of "Need for Speed" players say they have purchased music after first hearing it in the title.
