I've been out of touch with the blues, mainly because I can't stand the repetitive tunes that are stuck in the rut of (mostly) A, A7, A sharp, with the occasional adventure into E major and D major

And their lyrical content also tends on the sadder side of life. A female colleague once asked me to give her some happy songs. At that time, it left me scratching my head as to what she meant. Now I know the blues would not make it to her playlist
Just to be clear, I still do have lots of blues CDs and listen to them occasionally. They have their time and place.
The above is not to belittle or degrade other's choice of music. I totally respect other's choices. I'm just chronicling part of my own personal musical journey.
