Actually, most of them were planned on being for a harvest moon game i was making a long... long time ago. Most of these music pieces were inspired to portray a video or a scene.
The first one, crazy castle, was actually a boss battle scene (yes.... my HM was a bit different than the normal HM stuff:P)
The second one, fallen sorrows, was the ending... the character dies XD
The third one, happy village, was going to be a typical village song for the spring time.
The fourth one, relaxed medly, was just a medly of a bunch of jumbled tunes i couldn't get out of my head, and i refined it to make that XD
The last one just came to me... It was actually going to be used for a crappy FPS trailer, that was sorta like a sci-fi doom/bond-goldeneye 64 XD
I've done a lot more, but thats the only stuff that i've actually bothered to attempt to record with my crappy laptop mic
