K.K. Blues, I Love You, Spring Blossoms, K.K. Stroll, and K.K. Disco are my top 5. :>
I Love You is just such a pretty song, and K.K. Disco reminds me of a Billy Joel song and a nameless 70's song stuck together.
Well K.K. bossa is my favourite. Not because I like the way it sounds, but because of the childhood memories I have with it. I never knew how to get music in my house, or that it was even possible until Goldie moved in on my old WW game - it was the first song I got from K.K. too.
In terms of how things sound, I'd say either Hypno K.K., caf? k.k. And oh I don't know there are just so many.
