Chicago's Playlist - our hometown records

As their 40th anniversary approaches, Chicago magazine ranks "the 40 best albums ever by Chicago artists,” [by Jeff Rudy].  I own just one of the records. The Chicago Transit Authority’s self-titled 1969 debut album.  The band name was later shortened to just Chicago.  As for the other 39 on their lits: By artist, from 40th on up: Paul Butterfield, The Buckinghams, Local H, the Impressions, Screeching Weasel, Ramsey Lewis Trio, Eleventh Dream Day, Koko Taylor, The Jesus Lizard, Muddy Waters, Grupo Montez de Durango, Styx, The DJ Fast Eddie, Material Issue, Howlin’ Wolf, The Chi-Lites, Neko Case, Mahalia Jackson, Lupe Fiasco, Ministry, R. Kelly, Chicago (above, at no. 17), Big Black, Earth Wind & Fire, Cheap Trick, Herbie Hancock, Tortoise, John Prine, Kanye West, Andrew Bird, Louis Armstrong, Liz Phair, Curtis Mayfield, Muddy Waters (again), Naked Raygun, Smashing Pumpkins, Willie Dixon, and at number 1: Wilco’s Yankee Hotel Foxtrot.  The magazine defines a "Chicago record" as a nonclassical recording by an artist who is local by birthright or who adopted Chicago as home, or at least lived in town, at the time the recording was made.  Does anybody really know what time it is - care?
