Not in the slightest. She could barely name 5 bands I listen to regularly.
My personal opinion is that some of the comments here are putting a little too much emphasis on musical tastes.
I must've married Cool Chris's wife's sister.
For me, though, it's really two different questions. You can have "enthusiasm" for music, and not like the same kind of music. My wife does have an enthusiasm for music, just not Kiss and Night Ranger. Hahaha. I note that her enthusiasm is expressed differently. I'm the completist, I need every song that Genesis put out, even that green Flexi-disk of Firth of Fifth Live from 1982 that has never been officially released on CD... she's content with Keith Urban's catalogue on Spotify or Rhapsody or some such shit. For us, it's the enthusiasm - and thus mutual respect - for the music that's important. Franky, I kind of LIKE going to concerts myself. I get to watch what I want, I get to move closer if I want (or, like at Schenker last week, move back and mingle). I get to hang after the show (and I got to meet Gary Barden, Billy Squier and Dr. Allen Sloan that way) and I get to experience it the way I want to experience it.
It's not the place, so I'll tone it down, but this notion of "musical taste" as something tangible, or worse yet, quantifiable, is nauseating to me. I have four kids now, and for me, all I care about is that they like SOMETHING. Whether it's Lil' Wayne, or One Direction, or Iron Maiden, it's not the point. That I like Dream Theater or Neal Morse doesn't make me any better than someone that likes Cardi B or Migos.
