I am old. I was born in the very late 50's... so clearly, I have no real affiliation with music from the '50s except for my parent's deep affection for late '40s and early 50's music.
60's - Beatles... I fondly remember one of our babysitter's and her friends coming to our house to watch the Ed Sullivan show and screaming with them, although I had no idea why.
70's - High School... loved much of the 70's music, including the BeeGee's even though it was uncool to like disco.
80's - Post high school and college. As with many others here, lots of partying and good times. I find it curious that I can no longer STAND much of the music that I liked from the '80s
90's - love lots of music from the '90s. I got married, and my taste in music began to migrate to the music my husband loves... lots of Metal. James Taylor and Kenny Loggins no longer did it for me.
2000 on - It's hit or miss. I learned to love music from the past... Aerosmith, Led Zepplin, The Who, etc. I can't stand Pink Floyd... I know.. I'm a freak. I'm not into jazz, rap/hip hop, techno, etc. My tastes are eclectic. If I like something, I download it.
