I think Warrior is likely correct in assessing what era will appeal to most.
When I was a kid, in the early 70’s, we had an AM radio, and very few choices. We didn’t have money to buy records. I remember how great it was when you heard a favorite song being played. I was a notorious trash looker. I got my first bicycle by scavenging parts from the neighborhood garbage. I also got a few records from scrounging through the trash. My big scores were Janis Joplin’s Pearl and The Doors Morrison Hotel - and Black Sabbath Paranoid. Nothing was like Sabbath!
The late 70’s didn’t do much for me musically, with the disco influences. I was largely into Led Zeppelin and Sabbath, and disco seemed like it was too soft.
As the 80’s came along, music seemed to change, as MTV became popular, and there was some music that I found enjoyable that was also popular.
The 90’s were a bit odd, as grunge seemed to be a poor substitute for real metal. So, that wasn’t a favorite of mine.
However, with the rap influences coming along, and big booties, there was music with some great beats, and good club vibes coming. The early 2000’s were good, and fun. There was more identifiable emotion in the music, and that was good.
I think my favorite era was the mid 80’s, with pop as music videos added to the enjoyment of the music. I could afford to buy cassette tapes and listen to specific songs too.
