you can take a look at his various performance song lists at:

and note that there's probably 10 or so of his biggest hits that he plays all the time then mixes in some others. i'll be seeing him in tucson later this month and i guess if he didn't play certain songs (IYCRMM, wreck, shadows, beautiful, CRRT, rainy day people, carefree highway, painter, damn this list is long) i'd be abit dissappointed - it's not that ANY radio station every overplayed his tunes.
