I am trying to find some ECS and WCS songs. Can anyone please give me a list of popular songs which you can do either ECS/WCS with? Thanks a bunch!

Depends abit on how you define popular music. Most of these were on pop charts at one time or another...a few Ideas off the top of my head:

East Coast:
Only the Good Die Young -- Billy Joel
Every Heart Beat -- Amy Grant
Johnny B. Goode -- can't remember who performed it!
Run Around Sue -- ditto
Steel Bars -- Michael Bolton
Enchanted -- Fleetwood Mac
Lovers Who Wander -- Dion
You Don't Mess Around With Jim -- Jim Croce
Maneater -- Hall and Oates

West Coast:
Downbound Train -- Springsteen
I'm the Only One -- Melissa Etheridge
Lovin', Touchin', Squeezin' -- Journey
The Other Side Of Life -- Moody Blues
True Love -- Pat Benatar
Thing Called Love -- Bonnie Raitt
You're So Vain - Carly Simon
I Heard it Through the Grapevine -- Marvin Gaye
I Never Loved a Man -- The Commitments
Brass in Pocket -- The Pretenders
Seduces Me -- Celine Dion
