Some of these are nifty enough that I wanted to share, especially since almost all mashups are available for free download. Check them out!

Clever Juxtapositions

“Monty Python’s Killer Queen”
Theme from Monty Python’s Flying Circus
vs.
Queen – “Killer Queen”

“If I Were a Free Fallin’ Boy”
Beyonce – “If I Were a Boy”
vs.
Tom Petty – “Free Fallin’”
I’d never heard the Beyonce song, either. It’s not important to “getting” or enjoying this mashup.

“Don’t Cha Want Me”
Pussycat Dolls – “Don’t Cha”
vs.
Human League – “Don’t You Want Me”

“From the Heart of Glass”
Blondie – “Heart of Glass”
vs.
Philip Glass – “Glassworks” (combination of Opening and Closing)

Wow, That’s Really Cool / How the Hell Does That Work?

“Never Gonna Give Your Teen Spirit Up”
Rick Astley – “Never Gonna Give You Up”
vs.
Nirvana – “Smells Like Teen Spirit”
video available here

“Black Butterfly Busters”
Ram Jam – “Black Betty”
vs.
Smashing Pumpkins – “Bullet With Butterfly Wings”
vs.
Ray Parker Jr. – “Ghostbusters”
The Pumpkins song is the “rat in a cage” one — you probably know it, if not its title.

“Mia Freaky Mamma (On a Leash)”
Korn – “Freak on a Leash”
vs.
Abba – “Mamma Mia”
This one, in particular, is hysterically funny.

Just Plain Awesome

“Hotel California Must Go On”
The Eagles – “Hotel California”
vs.
Queen – “The Show Must Go On”

“Toxic Starlight”
Britney Spears – “Toxic”
vs.
Supermen Lovers – “Starlight”
Give this one a try even — or even especially — if you can’t stand the Britney Spears original. The new background completely harmonically recontextualizes the song.

Pure, Jaw-Dropping Magnificence

“Fixicity”
System of a Down – “Toxicity”
vs.
Coldplay – “Fix You”
SoaD is a scream-into-the-microphone-while-playing-heavily-distorted-chords metal band. “Fix You” is one of Coldplay’s slower, more boring songs, and that’s saying something. The intersection between them is nothing short of epic, in all the senses of that word.
