Keep in mind, the lp didn't start being marketed until 1948 and 45's in 1949.
Robert Johnson's songs were released as singles on 10" 78's. It's because of this, most of the older songs are under 3 minutes. It's also why 3 minutes for a song became the standard for such a long time, even after lps cam into existence. The 12" 78's could hold close to 5 minutes.
Which goes to my point, if you're going to include a Robert Johnson compiliation on that list, Miles, and Herbie....you have to include Armstrong's Hot Five and Sevens....and in the top two or three if not #1 if you want to be accurate.
