I have always been very pop-culture-oriented to a degree that would probably make most posters here turn queasy.
It is not limited to nerdy/geeky stuff like Trek, X-Men, Transformers, certain anime, Buffy, video games etc., but it also encompasses a love for contemporary pop music and the celebrities associated with this. I will still groove to old tracks by boybands and girl groups, even if I've come to acknowledge the inanity of most of their musical output. I check out the charts periodically, and keep up with current pop music (again). Currently, there is no single artist that interests me that much, but I like listening to that Ariana Grande kid, Bruno Mars, Justin Timberlake, etc.
Some of my pop cultural special interests in the past have included: Transformers, Buffy the Vampire Slayer, Marvel comics, Neon Genesis Evangelion.
Incidentally, in the past week I've been listening a lot to early 90s soul music (think Keith Sweat, Babyface, Tony Toni Toné, En Vogue). I used to think a lot of artists from that era of soul/urban music were corny as all hell, but I'm really warming up to it now.
