I also realized something that's now bothering me.
Can you trick while grinding?
Ethno Circus had to grow on me. Back 2 Back was an instant hit, but I think most of the others just grabbed me right away, which is just part of the Naganuma style I guess.
And on the note of Ethno Circus in particular, one of the SiivaGunner artists mashed it up with Mambo No. 5 and I Got a Girl and I think it's one of the better things the channel has done. Also good: the single rip of I'm A Spy, the theme from Security Hall.
