road music to St. Louis and back

Listened to a ton of CD's driving to St. Louis and back this past weekend. Both 9 hour trips started out around 5-6 pm and concluded at 2-3 am; so I needed that music to keep me going. The demo's of the greens; greg brown, paul simon, lucinda williams, ina may wool, nanci griffith, there must have been plenty more I am spacing out on now. Come to think of it, where are those CD's now?
