I'm not stuck in a specific period, but I don't listen to the radio, just my own music, so I tend to just listen to only my stuff and stick with it.... since forever!
The Beatles (the last 6 months or so I've mostly been listening to each of their solo stuff though), but been a big Beatles nerd since I was 6 years old, shows no signs of stopping now.
80's Pop, a lot of the 1 hit wonder kind of stuff...
50's and 60's... Frank Sinatra, Beach Boys, Led Zeppelin
70's and 80's.... Supertramp, Rush, Queen, ABBA.... I enjoy a lot of vinyl from this era, cheap and easy to find
90's... Ben Folds, The Smashing Pumpkins, Dave Matthews, all sort of 90's alternative rock (you know, Soundgarden, No Doubt, that sort of thing)
00's....Not much, I graduated high school in 2001 and sort of fell off the "what's new?" wagon... I occasionally add some random poppy earworms into my playlist but nothing that I specifically follow. I did really enjoy The Killers "Day & Age" album in 2008 though (lol... 10 years ago).
A lot of Disney music... ;-) I also listen to a lot of Disney Parks ambiance music when I'm coding.
And lastly, I'm into film scores.... Danny Elfman, James Horner, John Williams, Jerry Goldsmith, Alan Silvestri, Basil Paledorous, Harry-Gregson Williams, etc....
