I think what Melampus is saying is that he wants you to use J-pop in your next vid.
I personally like the music in the first vid more than the stuff in the second vid, but it didn't really seem to fit the knife. Didn't detract from the vid for me at all though. I will say probably the best music selection I have heard in one of the vids I have seen (I think it was a fairly recent customer vid) was the Dr. Greenthumb instrumental. A little repetitive, but it added to the video and was used to great effect with strategic starts and stops throughout.
Here it is for reference: kohetsu-240mm-t4236.html
The backgrounds probably could have been better if you want to get picky, but overall I think it is my favorite vid of this type so far and I think it might be the way he used the music in the vid. It probably helps that I loved Cypress Hill as a teen as well... lol
I also prefer the shots in both vids where the board takes up most of the screen area and gives a nice contrast to the knife. My least favorite shots were over the glass top table and place mat.
Very good job overall, and very nice knife skills!
