Oh wait I just thought of one -
Every Sunday afternoon on one of our local classic rock/oldies stations, they dedicate the whole afternoon to a "legendary artist" or however they term it. They don't play solely that artist - they just play them a lot more (like 4-5 songs an hour for about 3 hours).
A few weeks ago I was getting ready to go somewhere and as I turned on the radio before I showered, I discovered they were doing FM for their afternoon legend thing.
I was very excited and that shower ended up being like an hour and a half long (lots of singing
).
