Building my repetoire. Advice for songs I should learn next?

I have been playing banjo a couple years but have recently seriously taken on the task of building my fiddle tune repertoire. I am planning on starting to go to alot of jams and conventions this year, and I know I'll learn many tunes from people I encounter, but I just want to have a good shared knowledge base to start with.
I was wondering if people had advice on which songs that they encounter very often which I should probably know.
Here is a list of fiddle tunes I already know or am currently working on:

Liza Jane
Cripple Creek
Old Joe Clark
Kitchen Girl
Shortnin' Bread
Breakin' up Christmas
Wolves a Howlin'
John Brown's Dream
June Apple
Red Haired Boy
Sally Goodin'
Ducks On the Pond
Cluck Ol Hen
Sugar Hill
Arkansas Traveler
Soldier's Joy
Mississippi Sawyer
Forked Deer
Angelina Baker
Say Darlin' Say
Backstep Cindy
Sally Ann
Julianne Johnson
Angelina Baker
