Must-play songs

Don't Stop Believing
Living on a Prayer
You Shook Me All Night Long
Ain't No Mountain High Enough
My First, My Last, My Everything
And something from New Kids on the Block (not sure which yet)

The Prayer
Thank You for Loving Me
You're my My First, My Last, My Everything
Born to be My Baby
A few Bruce Springsteen songs ( havent picked out which ones yet)
I am sure there will be alot more added to the list

edit:
I also forgot
Beautiful Day
Somewhere over the Rainbow (the version that was in 50 First Dates)

No Letting Go - Wayne Wonder
You're My Everything - Mary J. Blige
When I See You Smile - Bad English

And I'm going to have to find a way to make sure they throw in a Linkin Park song
