What, no Grateful Dead :-) Did notice a Joni tune there "You're so square baby I don't care" I like a lot of the songs that President Bush has on his iPod :-)
The Dead's best work was live and it was mainly recorded in analog. I have several thousand hours and I've been able to convert put it on CDs without any problem, but I think the essense would be lost if it was converted to MP3 format.
