Recommendations for Soundtrack mixes? (energetic)

I’m trying to put together some mixes of video game soundtracks that have energy and are easy to like. I’m making a two sets of seven, but I’m having a few problems with a few, because I can’t find enough good songs for some of the themes.

For example, Masquerade Mountain Mix is kind of based on plains/forest/mountain music, and I can’t find too many good tracks. Some good ones I have include the Kingdom Valley set from Sonic ’06, Frog Forest from SH, and two NiGHTs songs. Any recommendations?

Another one that’s giving me a headache is Dead Dog Desert Mix, because catchy desert music is pretty rare — any tips?

Thanks for looking!

Soundtracks remixed, I must suggest ocremix.org/ (http://www.ocremix.org/). Been going there for years, check out the compilations.
