I have 3 vinyl albums, still sealed, I purchased when released, put in my collection unopened and never got around to putting on my turntable.
The Rolling Stones - Undercover (1983)
Big Country - Peace in Our Time (1988)
Unsane - Unsane (1991)
At this point, I'll probably leave them unopened and just download copies to listen to (if I ever get around to it.)
