I recently made a song using not only my electric keyboard/piano and Audacity, but text2speech to "sing"/rap/talk the lyrics. You might want to fast forward to 0:25 if you don't like the beginning and want to get to the lyrics, and you should probably also turn the volume up a little bit. And the song isn't just about KDE, but some other computer-related things too.
