Silver Fox just put up a post about road songs. This reminded me of field camp. For some reason only one person had brought a Walkman and she only had a couple tapes of local underground bands (at least in the van I was in). Things were OK the first day of driving. From Tuscaloosa to OK City is mostly civilized. From OK to Taos is, as I recall more sparsely populated but radio stations were available. In the wilds of New Mexico radio stations were not so easily found. Unless you want to listen to stock auctions.
Our TA was driving "my" van and our first trip to a Walmart he bought 2 tapes - Best of the Doors and Songs You Know By Heart. These two tapes were on pretty much continuous play for the remaining 4 weeks. I know all those songs, well, by heart.
These wouldn't necessarily count as road songs by SF's rules but those two albums certainly were our road music. I like something singable for the road and/or danceable. I'm a great seat dancer. =)
What do you think of as "road songs"? What are some of your favorites?
