I listened to the first minute, then skimmed through the rest. I think it's sticking to the same beat too much. It's quite a monotonous 5 minutes. I'm listening through a pair of AKG K171 monitors, so I think the quality is ok. I don't like the timbre of the main 'hook line' and the pace of the track (not tempo, but flow) isn't quick enough imo. Like the ping-pong sounding bit though. It's far too thin in places too, imo. Not in a dramatic breaking down kindof way, just on a boring way. All opinion, of course, and trying to be a bit constructive. I normally like your stuff though, this is an exception! Edit: that's after a more careful listen to the whole thing.
