Only listened to v3 and the riff is the star, with the general 70s / 80s style energy coming next.
It does still sound a bit "mono" to me - could be my system. I also needed the lyrics in front of me (though that also has to do with the genre and so not a super massive problem).
The vocals aren't studio-sounding - but they are live-sounding and I think that actually really suits what's going on here. Seriously I think you could stick on some crowd noise and say "recorded live at the [insert punky venue of choice]" and it would work (don't ask me how to do this convincingly, though!). Just a thought.
Whatever, it's definitely fun to listen to - good music I would say.
