It's getting better. Over the years, there have been spikes where it was more easy to see someone with the same tastes as yourself in places. Now, thanks to this site it has happened on a regular basis. Shirts, patches, bags and things have been a good conversation pick up point though.
But in everyday situations, hmmmmm. I often meet people with fairly the same taste in music, these people tend to be from the US though and have moved to Europe, coming from local scenes of either the West or Eastcoast, so there is common ground musicwise. I guess there is some kind of magnetism happening??
Most people I get to know outside of that, are not that much into music. For them, all this stuff outside of the big radio is just that "un-easy NOISE" - and no, that's no compliment ;) So, even if you point out what all is going on beyond that, there is not much ground to break, cause music to them is one of those activities that is immature and not worth the time next to lookin up new car models or patios, or early on vacation planning - you know the important things in life.
It often goes that way: "Oh, so you listen to that Rock'n'Roll stuff?? Elvis and the likes?? Are you a Rockabilly whatever type?? You don't dress it! All that stuff is too old fashioned for me, hehe!" Exaggerated of course, but that's the sum of it. I don't wanna play smart ass with these types, so I just let it go. But there are people with which you can have good, interesting talks about this kind of music and it's never a show off show.
And yeah, if the tone is right, I try to get into a conversation in a record store about, um, that record, but like y'all said: I don't push it.
