Like how the start sounds a bit like a retro organ playing and then the dubstep comes waltzing in to make life interesting and entirely cheery. Sounds like a mathematical song as well, nice. What is the main style of this piece anyways though? Like how it starts to speed up later into the song too, gives a feel of having to speed up to complete a level in a game.
The drums are funky and fast here. I like the chilly digital feel of the synth playing in the song. The bass gives a feeling of coming up and giving all your friends some fun math stuff to do that isn't so boring. The dub sounds make this song even more interesting to hear too.
Overall, very interesting piece. Would make a nice album opener.
