I propose the following terms for common situations in music, as yet (I believe) unnamed:
The Streisand – in which the audience applauds after the first line of a song, partly to express approbation, and mostly to show off:
Mem’rieeeeees … [applause, polite cheers] … light the corners of my mind …
Kiss today goodbye … [applause, sighs] …
Revisited Revisited – the act of sitting down to listen to a classic album, only to discover that you already know every word.
Fool’s Gold – any song that is worshipped blindly by someone who was the right age when it came out, even though said song is a piece of crap. Named after Fools Gold by The Stone Roses, but other examples include Born Slippy by Underworld, November Rain by Guns N’ Roses, and anything by The Verve.
Boozical – a show that can only be enjoyed when good and drunk (cf. Mamma Mia, Cats, Miss Saigon)
Collapso – any West Indian music played by white people.
