First of all, not all of the wonderful music you heard can be bought or downloaded from somewhere. Then, if I said the background music of a lot of games (especially the ones categorized in adventure type) are really awesome, I think most game players will agree. So how to get them out from games for direct play or collection? This case, third-party tools are almost always required, and of which, a game audio extractor is preferred. As for recording game music, that's just a remedy way.
