Into The Score

If you haven't already you definitely need to check out a podcast called Into The Score - "the only podcast solely dedicated to the academic study of videogame music!"

The podcast is presented by music teacher and composer Kenley Kristofferson and uses a mix of audio and video seeking "to be an in-depth and academic look at video game music, exploring the composers, the pieces and the games that they’re written for!"

There are some great episodes available, studying soundtracks from both well known and less famous games, including Final Fantasy VII, Uncharted Waters and Shivers.

Also, if you can get your hands on some of the earlier episodes (like the Super Metroid and Mega Man 2 episodes) they're well worth a listen too.
