The whole set screams "Let's dial in 1976 and put absolutely no effort into it". And I like most of the songs, but sheesh... if Renee had put this set together the Snipes would've gone nuclear.
Well, sure, it's Top Ten Tuesday, he found a list of songs that were in the top ten on this day and played them. It's what Top Ten Tuesdays are all about, a document of a moment in time, not a creative effort.
It is unfortunate that A Fifth of Beethoven appeared in both the 70's instrumental set and this one (or either one, but that's a matter of taste). But the Instrumental set came before this one, and he may not have thought that far ahead to know that it was going to show up in the top 10 for this day.
