Really quiet.
That's going to be the first thing I point out, it's far too quiet and you really should check your levels. If you got any issues with peaking or interference with a higher volume, you need to look into getting that fixed, re-master the piece, because when it is as quite as this, it kind of ruins the feel of the track.
Not a bad track. It all does seem a bit random, I don't really know what "1990" has to do with the actual track itself. It could do with a bit more variation, as right now, it's mainly this one main synth running throughout the entire track. There is variation in the rehythmics and backing synths, and the ending is real cool, but with so few changes to the main melody synth, it feels a bit dull after a while.
It could also do with being... bigger, simply. Adding a few more layers, more ambience or more backing tracks in general.
