Sounds like the solo vocal is being overpowered by the other instruments; the issue doesn't happen when the vocals get harmonized. It could just be me though.
About halfway through I thought my music player had somehow crossfaded it back to the start. Must be my mind playing tricks. Oh, and is it supposed to have a silent gap at around-- EDIT: That was just me.
The Troggs - "Cousin Jane"
I got the weirdest look when I randomly sang out "Cousin Jane!" once. Maybe the guy coincidentally had a cousin named Jane...
I kept waiting for a straightforward hi-hat pattern to come in, but it never did. That's the only thing keeping me from shaking my ass... and maybe that's a good thing.
I had to boost the gain in Audacity to properly listen to it, but yeah, this is neat. Glitches aside, the percussion seemed a bit mechanical, but I'm sure you're aware of that and will tackle that issue anyway.
