Hearing "Time Warp" played over the Wal-Mart PA/commercial/music system was very odd. Plus, there are few people at 2 am interested in jumping to the left.

They also played that "David Duchovny, why won't you love me?" song. I hadn't heard it before, so it was funny. Still odd choice, though.

I suppose the explanation might be simple: Maybe they just did market research on their midnight-5am crowd.
