Hey,
We had considered making Metroid Prime 3 our soundtrack of the month at Music4Games, but it didn't go through. I decided to go through with my idea to do an audio journal, however, commenting on the audio, and specifically the soundtrack, as I progressed through the game. We published the first article covering the first 25% of the game on 08/30:

We published the 50% mark on 09/12:

I just finished the game, and am going to do another article highlighting the audio in the last half. After that, we're going to have a little surprise for everyone... it's going to be awesome. =)
Let me know what you guys think of this concept. It's quite new, and the fact that Nintendo is so bad about releasing soundtracks makes this appealing to me because I think the music needs to be heard!
