I play (& listen to) all sorts, depending on what instrument I'm on and my mood at the time. Also the audience: Standing in front of a folk club with a guitar and singing something from the Great American Songbook or the Jazz catalogue can be done (and I do occasionally) but usually doesn't go down well and you do have to be selective. Don't even think of singing something that Percy Grainger, Benjamin Britten or John Ireland might have written and called a folk song and as for something in a foreign language, well, I just can't imagine it, unless you count Gaelic (which isn't really foreign - probably less so than English come to think of it!). Mind you, Flanders & Swan goes down well (in moderation!).
On the other hand, I cannot imagine singing F&S to the audience at the fundraising gig last month when I played bass guitar in a band - Midnight hour, 12 bar blues, Rolling Stones, etc, was much more the mark. Nor an I imagine them being impressed by Liszt, Chopin, Bach, Haydn etc., nor by anything I might play on the flute.
I like listening to most things: Classical (of all periods, including modern), Jazz, Motown, Rock & Roll, Country & Western . . . Lots really.
I'm not fond of Brass or military band music, and definitely not fond of Bagpipes. Can't really get my head around gamelan. Likewise a lot of other middle & far eastern music, though I did buy a CD called something like "Camelspotting - the real Oasis" a few years ago and it is rather good once you get the hang of it.
I dislike the noise churned out by computer programmers and masquerading as music for the purpose of creating an atmosphere in a disco where it is impossible to have a conversation, this being one of the few genres that I would wish to have a conversation over.
Someone has already said they dislike rap music: Perhaps the only memorable line in an otherwise dreadful film called The Last Boy Scout (or it might have been Hudson Hawk, also dreadful and both starring Bruce Willis) is where a baddie says to Bruce Willis "I want to hear you scream" and Bruce Willis replies "Play me some Rap music"!
