I listened to this in bed last night and thought the massive might also be into it. Its an episode of the regular Radio 4 documentary about er, words!. This week was all about the origination of music (sub) genres.
Stuart Maconie is the main pundit essentially arguing that all the key genres (funk, rock n roll, jazz) are slang for er, sex. There's a trip to Fopp in Bristol and the lovely Norman Lebrecht chips in.
Grime, dubstep and garage all make an appearance. but surprisingly no mention of shambling, indiepop or twee though. (although Paul Morley did a brilliant series on Radio 2 last year about some of them)

Listen again as they say...
