Sorry, not all mashup work. Case in point, check out "mashup madman" William Maranci striping out all the chord changes from the classic Journey song and turning it into a monotone nu-metal track.
My favorite comments:
"Just because you CAN, doesn't mean you should"
"William was sent here to end humanity and this is his weapon"
"Sounds like my father playing his music loud against mine when I was 15"
Enjoy!
