Mashup-Videos has put together a list of their top 20 mashups of 2009.
This one jumped out at me – Phil RetroSpector‘s A Thousand Secrets
It’s a mashup of Leonard Cohen’s A Thousand Kisses Deep, Le Mystere de Voix Bulgares’ Pritouritze Planinata and Muse’s Ruled by Secrecy.
Mashups are often little more than audio puns, but A Thousand Secrets works on a many levels.
