Music Theory: Two Eagles' Greatest Hits

-As you may have heard, Their Greatest Hits by The Eagles is the best selling album in the history of the United States. Despite it being certified 29x platinum, it doesn't change the fact that, much like Jeff Lebowski, "I hate the fuckin' Eagles, man." Regardless, I have been consistently blown away by their respective solo efforts.
-I saw The Warriors for the first time a few weeks back, and it definitely lived up to all the hype created by the video game, numerous rap shout outs, and the pending remake. The movie's final scene (above) is incredible, partly due to Joe Walsh's anthemic "In the City". The song later became an Eagles hit, but it was originally recorded specifically for The Warriors.
-Don Henley is another Eagle who arguably did his best work solo. Henley's "Boys of Summer" is one of my all-time favorites, though like many of today's youth my initial exposure to it came from The Ataris cover. I guess Walsh and Henley have proven that, when it comes to The Eagles, the lame whole is not necessarily equal to the sum of its awesome parts.
