I really can't make a list here because Gord has a lot of nice quiet tunes one can relax and /or drift off to sleep too.
When I want to do so,I just put in Discs 1,2 or 3 from Songbook (4 has more "rock" on it and would keep me awake.)
I also just put in,"IYCRMM" CD or the UA Collection CD's. If I know I'm tired enough to just conk out,I can put on Summertime Dream or Sundown & Old Dan's Records (and maybe Disc 4.)
For the quietest tunes,I'd have to make another special tape. Been me. Later!
