Downloading music...

[treehuggerhikerboy]

i use kazaa lite (without the ads)...although I purchase cd's of the smaller bands, and usually see their shows (where they make the most money).

some artists that are conducive to roadtrips:

dylan (obviously)
josh rouse
martin sexton
colin hay (solo acoustic stuff)
willie nelson (old solo)
the nadas
the shins
nick drake
elliot smith
david gray
wilco
beth orton
patty griffin
i am kloot
jay farrar
johnny cash
led zeppelin
louis armstong
ella fitzgerald
ray charles
ryan adams and whiskeytown
shannon lyon
snow patrol
yo la tengo

top of my head...but most of these folks should suit your roadtrip well.
