Do you remember Hidden Tracks that were put in albums?

I’m probably gonna age myself here, but does anyone remember hidden tracks in CD albums? It was always a hidden track that if you listen past like one to three minutes of a song or at the end of an album and there would be like a secret song hidden in there. I think Korn had a few in their cd albums and From First to Last. I can’t remember others, but am I the only one?
