I just wanted to say I LOVED GoNintendo Radio, truly one of the best, most enjoyable podcasts to listen to--along with the regular GoNintendo podcast of course!
I'm a huge fan of video game music, and I am actually interested in working on game soundtracks some day, doing sound design or editing--not sure whether I would compose my own music. Unfortunately I listened to all 12 episodes in the span of a few days when they were all out, so I couldn't participate in requesting songs or the contest. I would obviously LOVE more episodes, however many you have time for.
I'd love to hear anything from Super Mario Galaxy and more from any Zelda game. I particularly love Gerudo Valley from OoT, and Hidden Valley from Twilight Princess. Those types of awesome songs that only play in one area of a game are often under-appreciated and forgotten about when sometimes they're some of the best music in a game. Also, while short, the music at the end of every dungeon (after you beat the boss before you exit) in Twilight Princess was SOO good. I would often stay in those end rooms for a few minutes just to hear it a few times. It's called Boss Room Calm in the soundtrack I have, and a slightly longer version of it is at the end, called To the Twilight Realm. Gerudo Desert is another good from from TP.
Those are a few requests for when the podcast returns, and I can give more when new episodes start coming out more regularly. Please post more episodes before the summer is over if possible!
