Had to laugh at the beer thing lol
I once got lambasted by a Scottish friend for drinking Kronenburg - apparently lagers are a "waste of time" o.O
Anyway, back to the music thing... I was a snob when I was younger. I "hated" pop, I "hated" rap, I "hated" blah blah blah. By the time I was in my late 20s, I'd come to appreciate pretty much everything.
I ended up going to SOAS (the School of Oriental and African Studies) to do a music degree, and everyone had to learn to play one instrument, but it has to be a non-Western one, so I chose the mbira (African thumb piano, but it's not a piano at all... it's a lamellophone). I chose it because, when I looked back at my western music upbringing, I'd deliberately avoided "black music", so I believed my sense of rhythm and lyrical ability were severely lacking - and I was right.
Fast forward 8 years... and I can now play the drums lol. My sense of rhythm and coordination from playing the mbira allowed me to push myself as a musician. And from that point on (back in 2001 when I started that music degree), I just stopped being snobbish.
Of course, there are many kinds of music I don't like the sound of, but I no longer diss them as "not really music". I love rock, metal, and electronica - and I know lots of people who don't deem rock to be "real music", never mind the metal or electronica!
