Well i have a song from a SNES game in Midi form which is only 6kb for a 56 second go,
however you can't load into Starcraft as a midi [i assume]

However converting it to Wav for me leaves it at at least a hundred KB,
is there any way to convert it, with having a very minimal change in size?

You can compress it more, the best file type for SC is 16 bit mono, for one, make sure it's always mono, since SC plays stereo wavs as mono anyway, and from there you can try reducing the quality until it's a the size you want, remember that with 16 bit, it will be smaller in the map than it is as a file, but not too much.

Use Windows Sound Recorder to do all this, forgot to say It's built-in, Start>All Programs>Accessories>Entertainment

Hmm well cut its length to 10 seconds and got it to 75 kb :E
It may work, just have to decide if 75kb [total 450kb mapsize] will be worth it :]

You can reduce sampling rate to 11 or 8 kHz

Save it in Audacity using 16 bit mono at 11 or 8 kHz sample rate (just repeating what has been said). The smallest you can get is 16 bit mono, 8 kHz sample rate.

You say it's 56 seconds:

The bitrate is:
16*11 = 176 kbps = 22kB/s => 1232 kB
8*11 = 88 kbps = 11kB/s => 616 kB
16*8 = 128 kbps = 16kB/s => 896 kB
8*8 = 64 kbps = 8kB/s => 448 kB

MPQ archives 16 bit audio, generally at less than half the filesize, so use 16 bit to make it smaller, with a better bitrate. Take a look and see if you like how 8 kHz sample rate sounds. If you like it, go with that. It sounds to me like you are using 64 kbps, so redo the recording, and save it as 16 bit, 8 kHz. At 10 seconds, it will be 160 kB, but it will compress down to smaller than half.

I'm pretty sure MIDI works by simply calling WAV files and playing those, which is why it's so small.

Lies! Lies and slander!

Compressed audio to 11.025KHz 16-bit Stereo using WSR (Windows Sound Recorder).
Imported using ScmDraft 2 with compression set to highest (default).The quality doesn't drop notably after the import compression.

Original size: 2533kb
Compressed wav size: 634kb
Map size after imported compression: 208kb

And yes, it plays in stereo (I picked an audio clip that's easy to determine this [only drums are heard on the right side at the beginning]).

On a side note, make sure that your wav file doesn't have any spaces in the name. (Example: Change "My music.wav" to "My_music.wav" or "MyMusic.wav"). If you don't, it's possible to run into a problem, such as the wav not playing when requested.

Wow, if it actually play in stereo we have been living a lie for so long. HERESY! THE EARTH IS FLAT!

Not exactly wav files. MIDI capable soundcards (basically all) have so called wavetables which store the different voices/instruments defined by MIDI standards. These voices are not premade and stored, but generated each time with the correct tone pitch. MIDI songs always sound a bit different on different sound devices because they use different methods to create the voices.
