I don’t know what’s considered oldies, but for me that would be the 90s. I’ll listen to some 80s, but virtually anything before that is not on my playlist.
Wow, the 90s seems like “new” music to me, but that’s probably because I’ve always like the hits that were before my time. The official “Oldies” category has shifted some, but its core still remains the 50s and 60s, and now reaching into the 70s.
I have always considered the term Oldies to apply to pre-Beatles Top 40 tunes. However, my own tastes go back much further.
My personal Top 10 chart is currently comprised of songs from 1926-1932--and it changes periodically. The current #1 song is The Waltz You Saved for Me by Wayne King, which edged out last month's chart-topper Have You Forgotten? by Ted Wallace, now sitting at #2. Both are from 1931.
