I wrote earlier on the connection of the singer singing his/her song and the blogger writing his/her blog borrowing one of Neil Diamond's songs to riff on.
Yo-Yo said: "So much of human expression is longing. You're trying to go toward something-- some sort of vision."
Kabir said: "When the guest is being searched for, it is the intensity of the longing for the guest that does all the work."
This intensity by another name is called passion. It powers the voice to do wondrous things.
Halley said: "And the way he downshifts into the rhythm of the words 'I know you like it like that' -- the whole beat changes and if you could write it out in musical notation -- well, you never could, it's exquisite the way he does it."
I believe that is does not matter whether the voice is hip-hop (Ludacris), or written (Halley), or instrumental (Yo-Yo), or any number of other artistic expressions; if there is passion driving it, it is wonderful.
It is not work or play, it is exquisite!
And that brings us joy, joy that reinforces the cycle, so we can go on.
