I have noticed that guys (in general. There are exceptions. And a lot of women are like this too, though I've noticed it mostly in men) have a bit of a quietly smug superiority complex about their music taste. They also think they are fairly unique in what they listen to.
Now just to clarify, I am one of the worst offenders. The most scathing insult you could ever give me about what I listen to would be to say I was narrow-minded. Ohhh man. My skin would turn green, muscles would grow, clothes would rip. Right now my instinct is to list off all the many genres of which I am savvy. But that would be uncouth.
Another thing about guys and musical taste is that they are very, very predictable. Ask a guy what they listen to, and I will guarantee you they will use the exact same word. Every time. You know what the word is don't you? Eclectic! Another frequent term used is 'a bit of everything'. The painful thing is that I use the 'E' word every time I'm asked, while smugly thinking I'm the only one of my species using the word accurately.
But we love to use the 'E' word, for in a few heady syllables it says 'oh, I could list all the many multitudinous widely varying styles of music I listen to, but it would potentially take all day, for they are so many, and you probably wouldn't have heard of them anyway'.
I guess what I'm wondering now is, does it make you any less of a music taste tool if you realise and admit you are a music taste tool? Probably not sadly.
