I think the songs works much better with the glitches, but it's still pretty good. On it's own without any glitches the section from 1:30 to about 1:40 sound really weird to me, like something's missing. Maybe a slow down before coming back to the main melody and then coming back with a bang could have worked well? I also definitely like the main melody, and think it'd work also in a more classical piece, like a piano solo at around 80bpm.
