If it's only '75-'87 +
The Dance:
1. Blue Letter
2. Oh Daddy
3. The Ledge
4. Angel (1979)
5. Brown Eyes
6. I Know I'm Not Wrong
7. Fireflies
8. That's Alright
And if concert favorites count:
9. World Turning
10. Silver Springs
11. Sisters of the Moon
12. I'm So Afraid
And if
Say You Will stuff counts, I'd sneak in:
13. Say Goodbye (live version)
And if I could go double disc:
14. Sugar Daddy (!!)
15. Second Hand News (though it did get radio airplay)
16. Never Going Back Again (though it was covered on Glee

)
17. Storms
18. That's All For Everyone
19. Beautiful Child
20. Never Forget Tonight
21. Straight Back
22. Bleed to Love Her
And if Christine's and Stevie's songs from the early '90s count:
23. Behind the Mask
24. Freedom
I'm low on Christine because I favor her stuff before
Tusk, and a lot of the ones she had on
FM '75 and
Rumours were hits so they don't count. If her '71-'75 songs counted she'd have more but it would be really hard to keep it to 10-12 songs too.
Lindsey's
Tusk songs give me trouble because some of them are so interchangeable to me. Biggest example is "Not That Funny" and "What Makes You Think You're the One", not that they're the same song of course but they give me the same sort of value as a listener, so I ended up including neither out of indecision.
If I had to include a
Tango song it'd be either "Mystified", which I think is really pretty, or "Isn't It Midnight", in which I can see the appeal even though it isn't a personal favorite.
