Well there's a bumper sticker/quote isn't there?
"Grab a teenager while they know everything"
My Dd is generally a lovely lass, but she is now in her first year of post school study and studying subjects:areas I am very knowledgeable and even qualified in (which she knows!) and is still trying to tel me black is white on occasion!
I'm just backing away from the conversation at times and saying "ok we'll leave it there for now..." then when she's calmed down she's apologetic.
On at least one occasion she "vented" to her bff from school who knows me very well (they were very close at school and her family only lived a few streets from us so the girls basically lived at one house or the other) who apparently promptly set her straight and told her to get over herself! 
It is quite amusing when she starts sentences "but you don't understand..." when she's discussing a piece of research I'm especially familiar with and she's just started reading!
I remember reading one thread here ages ago where the ops son starting at uni did something similar in reference to a chapter in a textbook...that she'd written!
On music my dd is out of her time anyway, she's always preferred 80's and even some 70'e music to more modern stuff, I listen to a greater amount of modern music than she does. She is also a bit of a Luddite and would rather use a notepad and pen than a phone or tablet, I'm quite good on modern tech and she messages me "how do I do x on the phone?"
She uses a wall calendar, paper diary and wears an analogue watch, there's a running joke along her friends she's actually a time traveller from Victorian times!
I remember having a shocking sort of epiphany about older generations myself as a teen when I finally tumbled that not only mum (with me) but also both grans were pregnant when they got married. I well remember my mums mum (after recommending and watching with me a film with some rather raunchy scenes in!) saying to me laughing "younger generations always think they invented sex, desire...how do you think previous generations had all the babies they did?!" She was fab!
She also "outed" my mum for lying to me about her supposed angelic teen years when she overheard a conversation between us..."who are you trying to kid? I couldn't keep you in the house at night from you were 14! You coming home from a night out was dad and i's morning alarm!"
I remember doing it to my dad when he tried patiently to explain to me that some of the amazing music I was listening to were cover versions of songs from his youth
Ohh yes, I had a few incidents like that! I remember singing along to various 80's hits and parents joining in singing next likes and me being like "how do you know the lyrics? It's just been released!" And them laughing and saying "aye right that's an auld song" and in one case they'd been at the first live performance of said song! I knew nothing!
Yanbu op, sometimes they need stark reminders that you are human and not "just mum"
