Don't get me wrong, the show poked fun at pop cultures during its early seasons. For example, the slang (Bart's phrases), Michael Jackson was referenced a bunch of times, hell they made a lot of references of the past such as Citizen Kane, The Twilight Zone, King Kong/Godzilla, Nightmare on Elm Street, the obscurity of manual labelmakers. I don't mind the poking fun at pop culture of today but I feel like it's being shoved at the face of the viewer instead of being entertaining. They're taking it to episode titles too. Some make sense, others...well...look at the opening that lip synced to Ke$ha's "Tik Tok" song.
On the other hand, I don't mind the new "HD" opening too much. Would make sense after twenty years. A lot of anime (with possibly the exception of Sailor Moon 1-4 in terms of music) change their openings every season with new songs and new opening or closing sequence.
