Definitely drum n bass.
This track has some good beats and melodies mixed in. Though, The snare drum that comes in a few times and up tempos to lead into the rest of the beats is a bit out of place for such a breakbeat heavy track. The drum loops only repeat and don't slice up at all. Also, the whole thing sounds like a few different tracks strung together rather than one complete song. Personally I would like to hear some melody coming from some other source than the heavy bass synth.
Not a bad piece... great dnb feel... though the beats and melody just repeat over and over again... not much to it in that respect.
Nice work.
