The only scenario in which I would consider group sex would have to be with the boys from Gomez. They transcend genre. Well, mainly Ben Ottowell's voice does.
The 2000s became quite literal in the music and sex link, perhaps peaking with the absurdly named 'Promiscuous Girl.' (Tangential, but if you ever want to stare into the abyss, hunt down a clip of Nelly Furtado laughing.) I mean, sex and music were always close (I once made a passionate case that 'I Want To Hold Your Hand' was actually about fisting) but there used to be some mystery in the relationship, largely through the use of figurative or incomprehensible language (zigazig ah!). Apart from Gomez, the 2000s were a pretty unsexy decade for music, as far as I am concerned.
Prove me wrong, Clashtalk. Post your 2000s sexytimes music.
