If you're interested in a few free soundtracks, some of the most surprising examples are available in that vein. City of Heroes' entire musical score is available via ftp, for example, while the late Auto Assault has its entire soundtrack still on Fileplanet. EVE's soundtrack is online as well, and if you have EQ2 installed you already have the mp3s right there on your system. Non-players can also download it from these here internets. As commentary on the whole situation, Angus has a great angle on the subject: "I can totally see how the music for a place could make it popular or unpopular, in a game that had really good music in other places (so that the players didn't just turn it off)."
