To Leeneia (the following notes are subjective, i.e. I can be wrong):

Peace in the Valley: that's a spiritual with some optimistic hopes but no classical blues.
Since a met you baby: More bluesy and with a strong tendency of feeling happy.
I get a kick out you: First recorded by Ethel Merman with many follow-ups (Sinatra twice aso).I really don't know whether this can be characterized as (happy) blues. It's about cocaine, isn't it? Sorry, but I even can't remember the tune (I'm german). Therefore I'm not able to make a judgement.
Many thanks for your contribution!
