For some reason, guys who do Mario Paint music have this aversion to making MP3s of their work. Not to fret though! There's a way round it!

Double-click on your Volume Control.
Click "Options", and "Properties".
Click the radio button for "Recording".
Check all of the boxes.
Click OK.
Now select either the "Line In" or "Stereo Mix" box along the bottom of the window: This setting makes it so that your microphone will not work. Anything that records sound (even voice messages in chat rooms) will instead record all sound being made by your computer, including system alerts. Keep the volume low, but not all the way down.

Open some sound-recording software. If all you have is Sound Recorder, you'll have to start again a few times as you normally only get sixty seconds: Just record sixty seconds, stop your music, rewind the recording and start recording again: You'll get two minutes this time.

Now, play it back to check the sound quality. If it's no good, go tweak your recording settings again.

Then, the easiest way to convert it to MP3: Download a program named CDex (best CD-ripping program ever!) and use it to convert your WAV to an MP3.


Mac users? Can't help you, sorry.
