Besides mashing up music I also like mashing up the respective cover art.
This track is a mashup/medley of LCD Soundsystem and about six Daft Punk tracks. I created the cover art by finding this graphic of the dude from LCD Soundsystem holding Daft Punk puppies. I gave him some glasses added the writing in the background and added some (by now outdated) contact info.
Check out the track itself.
The download link on demodrop should still work, too.
