I had an idea for a mixtape (on CD, but work with me here), and the first thing I did was run a database query for Charting Songs Mentioning Friday, 1950-1994. Got 14 hits, which seemed reasonable, so I proceeded across the calendar:
Of those five Thursday tunes, incidentally, only one mentions Thursday in its actual title: “Sweet Thursday” by Johnny Mathis, which I didn’t have on the shelf. I had no problem with doing more recent songs, but it was apparent that I was going to have to do some shopping as well.
Two hours and three dollars later, I wound up with 2½ Weeks, which runs Friday through Thursday, Friday through Thursday again, and then Friday through Monday. This last segment is technically not a half a week, but four-sevenths, but at this point, I’m not overly concerned with rounding errors, if you know what I mean, and I think you do. And no, I didn’t hunt down the Johnny Mathis track.
