Full disclosure: I am, in general, not a fan of hip-hop, rap, or R&B. Every now and then a song will come along that I enjoy, but overall, those particular musical genres don't appeal to me.
It is, then, perhaps not surprising that I should find whiter-than-white covers of classic rap songs more amusing than others might.
(Why am I writing like this? Because I just watched several hours of Hugh Laurie and Stephen Fry being veddy British in Jeeves and Wooster. Good stuff, what!)
I discovered Jonathan Coulton earlier this month, thanks to Dr. Demento opening a recent show with Coulton's cover of "Baby Got Back" (requires Flash). And today, after perusing The Torontoist's much-blogged-about article on cover songs, I found Nina Gordon's acoustic "Straight Out of Compton" (2.1MB mp3). Both are brilliant. Note, however, that the latter contains explicit lyrics and frequent droppings of "the F-bomb," and the former trades in graphic euphemisms for a myriad of sexual acts. You may not wish to "pump up the volume" on these tunes while in the company of young children or co-workers.
(The other reason I'm writing like this is because I'm currently reading John Hodgman's The Areas of My Expertise. He is insane-- but in a good way, and thus we prefer to call him "mad.")
Speaking of the royal "we," I simply must link to John Rogers' agent's account of the Royal Premiere of Casino Royale (a.k.a. James Bond 21). If you've seen the movie, you can probably guess the central, er, nugget of his anecdote.
