My newest mash-up, made in one day after I finally found out what the song was they used in the season two closer of "The O.C." and recently parodied on SNL. Inspiration struck immediately. The result is as follows:
"Oohh, Whatcha Smell?"
Imogen Heap - "Hide And Seek"
- Vs. -
Nirvana - "Smells Like Teen Spirit"
