More like she's snobbish in the fact she has an almost encyclopedic knowledge of the music industry and likes everything. She like pop from over the last fifty years, most genres, and even foreign bands. She would probably tell you she likes your trash band,. but then start talking about their first album which was likely a limited release in their state/city/country of origin that only die hard fans would know but say it so casually because she's too dense to realize most people don't give a crap about that kind of stuff. She doesn't quite lord her knowledge of music over people, as much as she could probably walk into a used record store and school the snobby sales clerk about most bands.
