If the throne only has one seat, then it's simple - get 3 thrones.
You say this is 6/8, but in all honesty this piece feels very 3/4. It may just be me tripping myself over, but anything really distinctly 6/8 in here just feels like syncopation, especially with those drums. Only the part at 1:06-1:38 feels 6/8 to me, really. But hey, it's not like 3/4 DnB is any less cool!
And cool it is! The drums are very well designed, I love the rising and falling fast arps, the piano is very pretty and awesome, the progression is solid, and of course, I love the rhythm!
3MbeR mentioned that your bass should be in mono. Honestly, you've mixed this so well that I didn't really notice that as an issue. But I know from my own experience that widened basses generally don't work, so I'd try to steer clear of wide basses, especially in DnB.
Also, you didn't fade the outro all the way out :/ I felt the pain of that white noise suddenly cutting
Ha. "Easy Listening - Solo Instrument". Trying to be real sneaky, huh? Didn't fall for it, though. I read the tags first :)
Overall, very nice "solo instrument" track! You definitely have a lot of skill on that piano! 9/10, 5/5, good luck!
