Tonight I went to a local bar where a friend is the DJ. He's been doing it since the late 80s, so it's become sort of a tradition. The crowd is usually small, maybe a dozen, but there are various ages and musical tastes. He takes requests and will play anything from the Grateful Dead to hip-hop to Benny Goodman.
When he started he spun records on turntables, but as times have changed, he now uses a laptop computer with songs stored on an external hard drive. He can download songs he doesn't have and can also play songs on YouTube.
His playlist appears on the screen in iTunes, and at one point while I was talking to him I noticed "It's Friday" was in the list, about two songs ahead. I said, "NO NO NO NO NO! You're not going to play that?!" Turned out he had never heard of it. Some young guys on the other side of the bar had requested it as a joke. I had to explain it to him and tell him the story of how it had become an internet sensation.
Naturally, I requested "It's Sunday" to immediately follow it.
