COMPLETELY DIFFERENT MUSIC TASTE

Okay so me M(17) and my gf (16) Have pretty opposing music tastes, so im into artists such as: arctic monkeys, kaiser chiefs, blur , the smiths , the cure , fontaines dc , kanye west , pulp , the killers, j cole , stereophonics , lupe fiasco , people like them and more from that era . And I will stand on that being good music taste IMO.

However my gf listens to sabrina carpenter , Jessie Murph, gracie Abrahams, Ariana grande , Olivia rodrigo and the weeknd.

I can appreciate the Weeknd as I do like some songs by him, but she makes a huge thing that I have bad taste and that hers is better and often asks her friends to see who has better taste but they are bias ofc . It does get under my skin as Ik mine is better, I just cant stand the slop that her artists makes and she tries to prove everytime I see her that hers are better . Any advice?
