Ok first of all I have to agree with everyone who said that Harris calling chalk dust torture before the chorus was counter-productive. Anyway, here's what I think he should play for Scott. First of all studio versions only. Live versions are for people who already like the band and the songs.
The Wedge - good groove, lyrics are meaningless but don't sound stupid
Weigh - Music is interesting and sounds different from what Scott has heard. No Trey vocals. Lyrics can't really be considered "bad" (imo)
Split Open And Melt - One of the best phish songs ever, couldn't hurt to try it.
Horn - I think if Scott hears the whole song including guitar solo, he might like it. I just doubt he would sit through the whole thing during the podcast. Maybe play it for him off the air.
Axilla - Doesn't have that happy phish sound that Scott doesn't really like
Haley's Comet - How can you not like this song?
Scent Of A Mule - I think if Scott weren't already biased against phish, he might like the lyrics to this one.
