Neat story. The 2010s was the decade where I became a legal adult, and I definitely remember a lot of the stuff that was huge. I distinctly recall hearing "Gangnam Style" a lot when I went back to college for my second year, and I heard "Last Friday Night" quite a lot the summer after high school. Both very nostalgic songs for me, and while at the time I was getting my kicks elsewhere (Kanye, early Kendrick, etc), they definitely bring back memories of when I was a young man trying to navigate his path in the world (along with other huge songs of that era -- "Somebody That I Used to Know," "Rolling in the Deep," etc).
And my family definitely had very different, distinctive tastes, too. As a small child in the '90s who grew up in the 2000s, I remember my father having more classic tastes, while my mom was more aware of what was out there. My father had bands he liked at that time that were contemporary (Black Crowes, Dave Matthews Band, Counting Crows, Blues Traveler, Hootie and the Blowfish, etc), but they were definitely extensions of his classic rock tastes from when he was an early to mid-'70s teen, and some of these tastes carried over into what those '70s favorites were doing in the present (like Eric Clapton's Unplugged album, a favorite of his at the time). Meanwhile, my mom was really into solo female singer-songwriters (particularly after she saw Lilith Fair in 1997), Jewel and Sheryl Crow being two particular favorites (she also owned The Miseducation of Lauryn Hill, which I remember being played at dinner parties at our house-https://www.youtube.com/watch?v=syeudNRWsUQ
