I’ve had my Zevon list up my sleeve to see if it matched the first one posted - not one!
Warren Zevon
I’ll Sleep When I’m Dead
My Shit’s Fucked Up
The Hockey Song
Studebaker
Don’t Let Us Get Sick
Werewolves Of London
Play It All Night Long
Splendid Isolation
Mutineer
Frank and Jesse James
MiM
Transatlantic
Gee, that** was easy!
*Yeah, The Whirlwind is the name of the CD, but it’s really one 78 minute song divided into 12 (sorry, XII) parts. It should be heard as a whole, but if you want an excerpt, VII. Evermore is pretty nice.
**That’s every song on every “regular” studio release. If I was trying to convert someone, I’d play their “Live In Europe” DVD and, maybe, the Beatles medley from “Live In America”.
As a staunch defender and advocate of 70s progressive music, I would like to introduce…
Yes

Astral Traveller
Yours Is No Disgrace
Starship Trooper
Heart Of The Sunrise
Close To The Edge

Siberian Khatru

Mama
Home By The Sea
As I was writing this, I saw DfrntBreign’s post. Thank you: you’ve just achieved what this thread is about. You’ve introduced a great new group to me.
This is the only list that absolutely baffles me. I think Lanegan’s best stuff is on the 3 albums he has done with former Belle & Sebastian member Isobel Campbell - Ballad of the Broken Seas, Sunday at Devil Dirt and Hawk. So in keeping with the OP:
Top 13 Isobel Campbell and Mark Lanegan songs
Come on Over (Turn Me On)
Snake Song
Come Undone
No Place To Fall
You Won’t Let Me Down Again
Get Behind Me
Time of the Season
The Raven
Who Built the Road
Trouble
Black Mountain
(Do You Wanna) Come Walk with Me?
The Circus Is Leaving Town
Teenage Fanclub.
Started with thirteen songs, quickly realized that wasn’t enough…there were about ten more I thought of including here.
Okkervil River:
(1) Black
(2) Westfall
(3) Okkervil River Song
(4) So Come Back, I Am Waiting
(5) A Girl In Port
(6) Red
(7) The War Criminal Rises And Speaks
(8) A Stone
(9) The Velocity of Saul at the Time of His Conversion
(10) Plus Ones
Bright Eyes:
(1) Let’s Not Shit Ourselves (To Love and Be Loved)
(2) The Calendar Hung Itself
(3) Arc of Time (Time Code)
(4) Don’t Know When But a Day Is Gonna Come
(5) Lua
(6) Haligh, Haligh, a Lie, Haligh
(7) Hot Knives
(8) Easy/Lucky/Free
(9) June on the West Coast
(10) Something Vague
No Daria love? I won’t be soothed. 
If I go the next 40 years without hearing “Werewolves of Londaon” again, it will be just about right. “Mutineer” and “I’ll Sleep When I’m Dead” just missed the cut for my list. I tried to just deal with 10.
Werewolves of London is overdone, but I like it OK. Roland the Headless Thompson Gunner has been my favorite since my friend sang it at a talent show in high school. And My Shit’s Fucked Up is so good and clever, but takes on so much more weight considering Zevon was diagnosed with cancer right after making this song.
I know what you mean - it’s just - we gigged it for years and it makes me smile thinking about that.

I tend to listen to whole albums at a time, not individual tracks, so tomorrow I might decide that all the tracks (not just Arrow) on Godbluff, for instance, are great and should all be on this list! As it is, I’ve confined myself to a song per album and that seems to work pretty well…

Ditto, and the mere thought of trying to select a top ten from their incredibly long and varied discography gives me a case of the vapors… but I’m going to try it anyway:
XTC (srsly, their exclusion standing as the most glaring, damning indictment of the Rock 'n Roll Hall of Fame for their lack of focus on rock and their kowtowing to mainstream markers of success):
“Difficult” doesn’t begin to describe it…
Hey Nonsuch, give us your list anyway. Go on… esp with XTC, there’s no such thing as a less-than-magnificent top ten, so go ahead! 
Hell yes! Come on Nonsuch - if you and The Scrivener and I get 1 person each to buy anxtc track, it will mean Andy can get 3 more toy soldiers and may be inspired to write some more!
Do it!
MiM
Provisional Shakira Mebarak list (I don’t have all her albums yet):
The Church, off the top of my head:
Shocker Khan and I met at a Barenaked Ladies concert seven years ago this month and we’ve both seen the band an embarrassingly number of times.
We actually just saw Steve Page’s solo show here in Chicago a couple of nights ago and it was fantastic. About 50/50 BNL songs and solo stuff. He did a couple off your list there, in fact… Old Apartment and Tonight is the Night I Fell Asleep at the Wheel. His new band includes strings and and horns as well as drums/bass/guitar/etc so the old songs sound new and fresh. “Jane” was amazing, as was “I Live With it Every Day.”
You’ve inspired me to do my own BNL list. Stay tuned!
