I read an article written by Sheryl Crow in an old copy of Vanity Fair magazine about road trip music and it inspired me to make my list. My requisite for RT musak is that I must at least tolerate every single song on the disk; no listening to the first three songs or skipping around, just put in the disk and listen straight through. Oh, and the songs can't make me drowsy, either.
Crossroads--Bon Jovi [call me a small-town midwestern hick, I don't care]
Yourself or Someone Like You--Matchbox 20
The Immaculate Collection--Madonna
Shake Your Moneymaker--Black Crowes
American Idiot--Green Day
Songs About Jane--Maroon 5
I'm sure there are others, but that's all I can think of now.
