I've long since moved on from my youthful glory days of 70s "Classic Rock" and "Southern Rock". I can still occasionally hear a tune from that era and get a smile. It had it's place in my life and, for the most part, I can look back with fondness.
I do have one major musical regret that causes me great shame that I can only admit in the relative anonymity of this forum...
STYX!
A co-worker plays the local classic rock radio station at work and they played "The Grand Illusion" album in its horrid entirety. I just couldn't believe I ever listened to that drivel. A "what-was-I-thinking" moment indeed.
