Sorry we’re a bit late in posting this month’s Bootie Top 10. Mysterious D is off at South By Southwest in Austin, Texas this week, and things have been a little cray-cray! But we’ve finally assembled a lovely assortment of mashups for your downloading pleasure.

7 out of the 10 mashups on this list were done by European producers, who are pumping out some quality work lately. No, there’s no Pharrell Williams “Happy” mashup here, because we’ve yet to hear one that really knocks our socks off. But we do have two “Timber” mashups (both produced by Americans) so …. there’s that. And just when you think you’ve heard every “Smells Like Teen Spirit” mashup, along comes this gem on our list, seamlessly blending a timeless disco classic on top. Sorted (mostly) alphabetically by bootlegger.
