It is a bit of a minefield being a musical snob, when you're asked this question. I tend to be very unforthcoming about what I'm into, instead prompting the other person to tell me what they like - at which point if I like what they like I'll enthusiastically respond, and if I DON'T like what they like I'll pretend I quite like it. Same thing goes when somebody in my office tells me how great The Big Bang Theory is.
Mind you, this applies with other music snobs as well - i.e. if I start talking to somebody and they reveal themselves to be into 'real' hip-hop - Mos Def/Kendrick Lamar/Gang Starr etc. or horror or horrors UK HIP HOP then I also have to bite my tongue and make loads of qualifications if I happen to reveal that I much prefer Gucci Mane to Jay Electronica.
It doesn't come across well if music is obviously a huge part of your life and you won't discuss it with someone
More than likely, it was "A-ha
look this ain't london where dance music + reggae + all kindsa weird shit is a noticeable part of the culture. if I said I was into jungle people would think I literally meant like sounds from a jungle (or maybe tribal drumming or something). reggae here=bob m. "weird electronic"=skrillex or if you're lucky daft punk or aphex. it is a neverending sea of norah jones and foo fighters and brad paisley, let alone the abyss of brostep and edm. this country is mostly a musical wasteland, even the big cities. I'm not demanding people be up on the most obscure coolest thing and I hate record snobs as much as ever but I'm also just not into explaining who the velvet underground or something is for the 500th time. as ory says, best to just change the topic. and seriously tho fuck some made up obligation to make musical small talk w/people just because.
(and not that it matters but i've never bought a record off ebay in my life)
a couple years ago I worked at a lab w/some younger kids who were REALLY into Tiesto and I played Acid Tracks for them
