"Hmmmm…your experience in this work industry is quite extensive. You're hired!"
I may be overly thinking this idea, but isn't knowing a lot about music in a sense the same as having a lot of work experience similar to a resume? The more music you know about the more righteous you'll seem. I'm talking about gooooood music, not that mainstream nonsense.
How about conversing with someone about the same music tastes?
"Hey, have you heard of (insert musician here)?"
"YES! They're awesome!"
"Wait, if you like them…you have to like (insert musician name here)!"
"Why of course! Who doesn't."
