Occasionally, a double album has one record with sides 1 and 4, and the other record has sides 2 and 3. Even after reading why this was originally done, I still think it’s ridiculous. With the description of the automatic changer, it seems like a lot of extra work to listen to the double album. Thankfully, it’s not that common. On the flip side, it’s so rare that I always forget and flip a record after side 1. When that happens, side 4 starts playing and I spent two songs confused about song order, then I just figure I’ll keep listening until the end of the side, then my whole rhythm is off for the day. That’s fun. I don’t have much rhythm as it is. Throw it off and you better take cover.
